Leaf Challenge: Regular Painting is Good for the Soul

It's New Years Eve and I forgot to do the food shopping, instead I sat in the kitchen and wrote my last post for the decade. It's all about snatching a little time each day to paint something small.  Picasso famously said 'Art washes away from the soul the dust of everyday life' so that can't be a bad thing to end the year on ....there's been a lot of dust this year! but another plus is that regular painting is the key to improvement. With this in mind I decided it would be good for me to power through some speedy leaf painting. Of course in an ideal world I'd love to spend more time painting but it's not always possible. Each year I try very hard to complete a couple of 'substantial works' that I'm reasonably happy with, sadly sometimes not much else is achieved other than demos for tutorials. So my self-imposed challenge last week was to paint a leaf every day within 90 minutes....'if possible' being the caveat.

Details from leaves painted during week one.
Why Leaves?
I love leaves! and it's the love of the subject drives the painter on to try harder to do better - and to never give up.  There are so many leaves too choose from, many are challenging with incredible diversity and detail, there's more than enough to keep a painter occupied for a lifetime. As Lucien Freud said ' it's what Yeats called the fascination with what's difficult. I'm only trying to do what I can't do.'
I hope to carry on with this challenge for a while and to be a better artist but being fickle, I can always swap to a different subject should he mood change.... for now leaves are good.  Here's the sum total of my efforts with some information on the process.



Green Photinia, leaf no. 1 This is a leaf with a deeply indented 'V' shaped profile - i.e. it indents at the mid rib. The light is coming from the right hand side. Yet note how the right side of the mid rib is in shade, so although the leaf catches the light near the outer margin, as it nears the mid rib it indents away from the light. Conversely, where to leaf bends upwards, on the left of the mid rib, the light catches the smooth surface, creating a distinct difference between the left and right side of the mid rib. It's at its darkest where the far left curls away from the light This left to right difference is a key feature of lighting that shows the 'V' shaped profile. 

I generally use a 4 or 5 stage process and bring the whole leaf up in stages. Top row: Stage 1. underlying colour (cobalt blue) wet-in-wet, the highlights are the most blue (not the shadows). Stage 2. Basic hue wash, (French Ultramarine, Winsor Lemon and Permanent Rose) wet-in-wet is used, the idea is to capture form from the outset. Work on one leaf blade at a time (here shown in 2 images). Bottom row: Stage 3. Add more selected washes, wetting/ dampening and adding colour only where needed rather than wetting all over. Use a slightly creamier paint mix, this selective approach enables me to retain and control the highlights. I also add that brown blemish with yellowing around it, the same colours are used to mix the brown and dropped onto a dampened area.  Stage 4. Modelling dry brush technique using a much creamier consistency of paint onto a dampened surface to deepen colour. Drawing dry brush is used on the slightly damp to define softer veins. Dry brush on damp creates a softer smoother finish but the water:paint ration takes a little practice to get right. Towards the latter stages I allow the paint to dry to a skin on the palette and use a damp brush to moisten, this gives me a much richer colour for detail.  I also pick out veins at this damp stage and sharpen up the serrated margin by wetting the edge and adding paint into the wet edge and blending into the main leaf blade. Stage 5, Fine tuning and tidying up, deepen where necessary using an effect that I refer to as 'polishing' using a very dry brush in a circular motion. Mostly painted with Betty Hayways size 4 and 7. The final touches using a size 2 Windsor and Newton series 7 miniature. This leaf took about 1 hour...if only they were all so simple!

Do try this at Home
If you are thinking of trying some leaves, don't worry too much about the time constraint or perfection but do try to finish a small work in one day.  For me, the objective is to capture the overall 'character' of a leaf; its shape, form, colour and surface texture. It's not so much about tiny details or photorealism but more about the 'feel' of the subject. Start to improve your observation and understanding of leaf shapes and surfaces within a very short space of time your drawing and painting will improve too. See previous posts by searching for the 30 day leaf challenge, which I completed several years ago.

Leaf no. 2. Another Photinia. Love the variation in these leaves. This is the red version found at the terminal branches, slightly weathered this time and curls back more, with less of a 'V' shape at the mid rib but still has some left to right difference and strong highlights. 
The process is  much the same as the previous leaf but with different colours.  Cobalt Blue first, then selective washes of reds and violets. The reds are: Scarlet Lake (warm) Permanent Rose (cooler pink /red) and Permanent Carmine (darker (warm red). Add some French Ultramarine to make the violet and a touch of Transparent Yellows in the mix makes those dark, almost black blemishes.

Can you see the Light: Technical stuff
As a tutor one of the most common problems the I see in leaves is a lack of form, flat looking leaves result from poor or diffused light - poor light kills a leaf stone dead because everything is painted using mid tones. To bring a leaf alive you need light and shade (i.e. a range of tonal values). If you're a beginner, the best way of resolving 'flat leaf' problems is to enhance that light, exaggerate it in true Chiaroscuro Rembrandt fashion but use modern technology by using a fixed light source from a lamp. This doesn't have to cost a fortune, any angle poise lamp with a swivel head will do, then fit with a photographers bulb E27 screw fit, use 5,500k (Kelvins) which is the nearest to natural 'white' daylight and easy are to buy on Amazon or from photography suppliers, don't look in art suppliers for bulbs, many claim to be daylight but are not. Bulbs over 6000k give yellow light and bulbs under 5000K are blue, so will not give accurate colour. You also need the correct CRI, (colour render index) of 90 or above or as near as you can get. Bulbs with CRI over 90 are more difficult to find and you may have to settle for 80 but the higher the CRI the better the true colour.  Light from the upper front left if right handed and the right if left handed, although I tend to light from the side the I think looks best for the subject. Pin your leaf to a piece of white foam board and light from your chosen side, move the lamp around to create good contrast. Try painting in black paint or ink first to avoid confusion between colour and tone.

Look at Ruskin's tonal studies for inspiration, it's all about light and shade, note the dramatic difference either side of the mid-rib. Study the masters!

Observe and Draw 
Make sure you get the leaf drawing correct, double check the typical features of a leaf and look at a few different ones if you're aiming for botanical accuracy, alternatively, you can just go with whatever takes your fancy, some leaves are more interesting than others, so choose wisely. Make quick notes on leaf shape, margin, tip and base, venation pattern and surface texture, measure height and width and note the widest point too as this can be a key feature, if you measure you can't go wrong. At this point , ask yourself what are you trying to portray, is it shiny, mat, puckered or hairy surface etc. Being accurate in your portrayal of any subject is important so never short cut the observation and drawing. Keep pencil lines minimal and light. I use a H grade for drawing.

Limited Palette with sufficient range of blues, reds and yellows does not impose any limitation on what is possible. I've been working with this palette for years. 

Painting Materials - what you need and what you probably don't need 
My palette is limited to primaries, this is the best way of working for me, it keeps it simple and I can shift a mix to warmer and cooler versions of the basic hue - look carefully and you will see how light affects colour across the surface of the leaf, this is where using three primaries really works because that colour shift is made so much easier by adjusting the ratio of colours in the mix.  There's no need to have the whole colour range from every supplier.  Heres my basic materials list for paints and everything else. With regard to paper, I'm not discussing Fabriano any more, yes there's a new one but I moved on anyway. I've  tried a few different papers in the last few years, it takes time to get to know them, I mostly used Saunders Waterford HP high white 300gsm - it's a decent enough paper which takes a bit of effort with the edges but is tough and the colour is good. Botanical artists tend to prefer hard gelatine sized papers, starch sizing is generally a little too soft. I'm a fairly dry painter and careful washes is the best approach and if you work dry, so you never need heavier paper than 300gsm, it's pointless spending money on the heavy papers if you don't need them and often they are not so smooth as the lighter weights ( Arches being a prime example, the 300 and 600 gsm versions are like two different papers). I sometimes paint on Schoellershammer 4G which is super smooth and lighter in weight but because work dry there is no cockling, sadly this is another paper that appears to be discontinued. Brushes, usually size 2 and 4 series 7 miniatures and a size 1 short flat synthetic there are lots available. I did switch brushes for some of the leaves, which were painted with synthetic Betty Hayways brushes, I used the larger sizes 4 and 7 which worked well, point and belly are good but the small sizes are less so and as with most synthetics the tip goes quite quickly but I found I could use the large sizes for everything, even the dry brush. Use an elevated drawing board so that you save your neck and can see what you are doing and finally, use a magnifier! x2 is sufficient, more magnification isn't helpful as you can only see a tiny area also excessive magnification hurst your eyes.

Starting to Paint
After making a very simple line drawing with as little graphite as possible on the paper. I begin with underlying colour, in green leaves this is usually blue, a high light value blue, such as Cobalt, Cerulean or Manganese. In red and brown leaves, yellow and violet can be involved too, so this can require an underlying blended wash of several colours. You will see this in the various step-by-step images.

Leaf no. 3 A shiny Camellia. The process: this time a blended wash is used first using Winsor Yellow and Cobalt blue. The rich green hue is made with Windsor Blue Green Shade, Transparent Yellow and Permanent Carmine. I also added a little Indanthrene blue for the darkest greens. This leaf was a big challenge in a short time, it took the full 90 minutes because of all the layering with the veins and dark shades. I used a piece of agate to lightly burnish between layers, which makes sharper edges easier. I could easily have spent another hour on this.
Finished Camellia

Work up the whole leaf, keeping the light with selective application of colour
I can't stress how important it is to work up the whole leaf in stages, this is how you capture the light and shade to create a dynamic painting.  If you try to finish little parts at a time, the end result can be quite flat and lacklustre, although it can start off ok, it often ends up disappointing ( I'm sure we all know that feeling). I work up all of my paintings in this way and the more complex the painting, the more important it is to attack as a whole. After the underlying wash I add colour selectively working on one leaf blade at a time. I dampen and add colour where needed, which avoids adding too much water and painting over the highlights, conversely, adding too much water in all-over washes flattens, loses highlights and creates hard untidy edges.


Leaf no. 4. An aged Oak leaf. Same approach but with underlying Transparent Yellow and Cerulean Blue in small parts, being careful not to overlap them, I carefully 'scumble' the blue in the highlights leaving some white, this gives the textured highlight, see first image. This was a difficult leaf and I can't say that I'm overly happy with it, having botched the highlight on the green. Have painted oaks before and used more warm violet in the underlying shadow layers so I think this might have been useful in the shade areas. Its Ok though but I'd approach it slightly differently next time, so lesson learned. The browns mix, Transparent Yellow, Scarlet Lake and Permanent Carmine with a touch of French Ultramarine, the green mix is made using the same blue and yellow. Looks slightly unfinished but I wasn't in love with this leaf.  

No. 4 Finished...sort of 

Depth and Detail
Once I'm satisfied that I've added enough colour using selective washes, which is usually only 2 layers after the underlying wash, I start to use different dry brush techniques. Sometimes I use a 'scumbling' technique for texture, I use dry on damp for smooth deep colour with creamy paint to 'model' the surface, for creating rich colour and shadows. I also use a 'sweeping motion' for long leaves and a 'drawing' technique on damp and dry for detail and finally a 'polishing' circular motion which is the driest, and creates the shine. I use much the same techniques on vellum but with fewer washes.

No. 5 Holly. Can't beat a challenge and holly is always a challenge! It's dark, shiny, textured like leather and with points that stick out at all angles! I put the initial blue wash down, using Cobalt and Manganese Blue, I love the manganese for those electric highlights!  Next I 'scumbled' on the green in patches, working between veins and into highlights to give that textured appearance of an old dark holly leaf, younger leaves are lighter and slightly smoother. This is a very dark green leaf, Indanthrene Blue, Transparent Yellow and Permanent Carmine were used. The initial selective washes of green were more of a yellow biased lighter green mix, it looks messy but stick with it. The later colour is dry brushed on, it has more blue and is darker, so, a more viscous mix of paint. 'Polishing' it on with a dry brush smooths areas. The brown mix for the blemishes is the same three colours just start with the red and yellow and add blue until you achieve the correct brown. The approach is much the same for all leaves in terms of stages though, keeping the highlights is vital in holly but they're a stronger blue than you might imaging so be brave with the initial wash, it pales away against the dark green. I used the agate burnisher between layers to shape up the edges. 
Leaf no. 5 Holly finished 

What you may have noticed is that the order is much the same in all of these leaves, there is some 'back and forth'  in terms of approach but its broadly the same 1. underlying wash, 2. Selective colour layers into wet (2 or 3 layers)  3. Depth and Detail with dry brush on damp 4. Finishing touches and review.

Leaf 6. Two for one bonus! the front and back of a Cyclamen coum leaf. Underlying blue is the same in both. Sorry I forgot to photograph the stages of the back but it involves a lot of Quinacridone Magenta, some French Ultramarine and Permanent Carmine. The patterned front is easier than it looks: underlying blue is Cobalt and Cerulean, paint in the veins and outer edge lightly using a green mix for the veins and a yellow biased mix at the edge. French Ultramarine, Windsor Lemon and Quinacridone Magenta is used.  Add centre pattern working between the veins by wetting the area to be painted first and use a stipple effect to blend into the lighter blue area between the centre ands margin colour which has more yellow in the mix. Build colour using dry brush. Put in the flash of magenta on the central vein and petiole and it's done! 


Process of the front in stages and the latter stages of the back.

Finally, I achieved the small goal of painting a leaf every day, simply by staying up for an extra hour at night or getting up a little earlier, which felt quite satisfying. I realise now that I could do the same with other work, especially if I also neglect the food shopping and other domestic tasks.
There wasn't much left in the garden by the time I reached leaf no 7. but I was determined to finish this. I chose an ageing rose leaf, which was pretty much about to drop all its leaflets except the green one, which was clinging on for life. This explains the missing leaflet on the left hand side. An interesting one to paint because I used 3 different underlying colours, blue, violet and yellow. I decided to paint this one on Schollershammer 4G paper, which is great for crisp edges and most like the surface of vellum - but use too much water and it will look like the mountains it will cockle so much. It's a great surface if you're in training for vellum and want to work dry. Alas, its a shame that it doesn't seem to be available any more as its my favourite paper for drawing too. Such is life.

Leaf no 7 Rose. My first compound leaf. A strange looking leaf from the underlying colours,  cobalt on the green leaflet and Cobalt and Quinacridone Magenta on the brown leaflet to make violet with Windsor Yellow on the Yellow ones. I used French Ultramarine, Windsor Yellow and Permanent Rose for all colour mixes. 


Thats all folks! .......until next year.

Wishing you a great New Year with much painting in 2020

Primary Palette Colour Mixing

It’s been a very long time but the blog is resurrected!

Having recently written a tutorial about colour mixing using a primary palette, I decided that this would be a good subject to kick start the blog with. A few years ago I decided to eject all of the unnecessary paints from my paint box in order to simplify the colour mixing process, if you’re wondering why I dismantled my beautiful looking paintbox,  I found I was only actually using a small number of paints and simply didn’t need them all, also, it’s so much easier to teach students using a limited palette and it puts a stop to the idea that you always need another colour in the palette. To prove that this was a good idea to myself, I removed everything that I felt wasn’t needed and attempted to mix the same colour using  primary colours, it was surprising to see how many of those colours I could match!

The streamlined paintbox on the left and all of the un-necessary paints can be seen on the right. I swapped half pans for full pans with the most used paints. 

Mixing and matching some of the colours with primaries, here are some typical paint box colours: the umbers, sap green the perylene's, quinacridone gold, some violets and there were many more!  In fact I had in the region of 100 paints including most of the W & N artist pan colours, which is frankly ridiculous but good for paint manufacturers! This exercise enabled me to remove all of the paints that I didn't need. I know that there are other properties that can't be exactly replicated but in most cases the primary mix was better (in my opinion) and there is the opportunity of easily shifting the ratio of colours to make it warmer or cooler and making a shade version, so further simplifying the colour mixing process. 
How a mix of 3 primaries can be shifted left and right of the basic hue mix (centre) to create a range of greens found in a leaf, simply by altering the ratios within the mix and creating a more natural shift to a paler warmer green  (adding more yellow) to a darker cooler shade green (adding more blue and red). This approach to colour mixing creates much improved continuity and transition in a painting and is a simple to learn. 

What is a Primary Palette
There is often a lot of confusion about what a primary palette is, the most basic form comprises just one red, one blue and one yellow, from which all secondary and tertiary colours can be mixed. However, a palette of just 3 colours will not provide the range of colours needed in many brightly coloured botanical subjects,  so if you've tried that and failed - don't be put off because paint is not like the light and you'll struggle to achieve everything! My primary palette is actually quite broad with 4 yellows, 5 or 6 reds and 5 or 6 blues, any less would be too limiting for me.  Since streamlining the paintbox I found that have a far greater understanding of colour mixing.   
If you want to see my palette choice you can find them in my suggested materials list on my website click here.
The old paints haven't been wasted though and I've given many of them away to those that still use them but I can honestly say I haven't missed any of them. 
Some of the paintbox survivors - reds, yellows and blues, checking out their light value and saturation here by painting from full saturation to a pale watery wash.

Making Useful Colour Charts
There is no point in making colour charts for the sake of it, they have to be useful. Once I'd removed the redundant colours, I set about making some basic colour charts mixing primary colours to make a wide range of secondaries and tertiaries, such as seen in the simple charts below. The first task included making secondary mix charts -  a yellow and red chart, a blue and red chart and a blue and yellow chart. For this I used 1:1, 2:1 and 1:2 ratio mixes which gave me a large range of colours which are warmer and cooler than the 1:1 ratio.
Then I add the third primary colour to those mixes, for example adding a small amount of red to a green mix, (made from blue and yellow) can create a more natural looking green but you can also shift the balance of the same three colours to make brown or grey as well as a range of greens etc.. It became very clear that this provides everything I could ever need. I made brown and black charts using the dark value pigments mixed using thick creamy paint mixes charts and grey and white charts, using high light values colours painted as tints.
The light value of the colours and the viscosity of the mix are all important too. But thats for another post.

Putting the Charts into Practice
To use these charts, I simply place a new subject onto the most appropriate colour chart as a starting point.  All the mixes have a warmer and cooler version of each mix and are painted in swatches which start at full saturation and then watered down to a tint.  Below are just a few examples.

A selection of colour charts and subjects painted using the charts mixes for guidance. 
Identifying the mix from the Green chart: Using the 'light value' of the Blue as the predictor colour for green mixes. This creates light greens, mid value greens and dark value greens, then shift the ratios of the mix to make browns by increasing the red and yellow. Simply drop the leaf onto the chart to match the colour. See the last but one post for more about the green chart
Using the same three colours to mix all the yellows, greens and browns in this Hellebore leaf by shifting the ratio of colours in the mix.

Of course there is a lot more to mixing and matching colours in a painting, such as the underlying colours and the effect of light and shade, which could be discussed here but I'll save those topics for another time. The 'take home' point is that that this method of colour mixing provides a great insight into the properties of colours, their light value and dominance etc. and makes it easier to achieve the range of colours in a subject with improved transition. Also, you only have to paint the charts once and thats it, no confusion over which colour to choose and its much more cost effective if you're on a budget. 

To finish, it seems a bit cheap to include only images of colour charts so heres a much shortened, sped up video of painting a white flower from the tutorial. It's hard to find good information on mixing whites. Often the advice is to use leaves behind the subject or to use the dreaded 'grey', which looks...well like a grey flower. In my experience, neither approaches are overly helpful as many flowers don't naturally sit in front of a leaf. In fact white flowers have many colours, they're just pale but first of all we have to first be able to see and identify those colours,(the charts help yo to identify those colours) -they have colour reflected onto their surface from the surroundings too, so there is a lot to consider. Using watery tints in deep wells is a must for whites as are high light value colours. But enough for now.


Finally, it's been over 10 years since I started this blog, things gave changed a lot both with social media, with my painting and teaching since that time. Blogs may be a little outdated now but I still have a soft spot for them. It's a great diary and journey for me to look back on (typo's included!). I've neglected it for the past 2 years  due to lots of other things, both good and bad but hope to make the occasional post again now that I've settled into a new home.
Thank you for reading
