CHAPTER 1 in case you missed it
Welcome back. Nice Hat!
We want to prevent chalky colours in our oil painting. Sure there are loads of ways to do this. I'm going to share a way that is one of the best methods I've stumbled on. And then I'll share my favourite, much easier way. Followed by an even easier way.
If you have a trick for preventing chalky colour mixing, please share. There are about thirty six thousand ways to do anything when it comes to oil painting. try some and see which one works best for you (then pop over here and let us know).
The right colour in the right place.
It's a mantra that seems to comfort painters. If we can perfect this art of putting the right colour in the right place, everything else will fall into place. It's a big fat lie, but it's a lovely lie that helps us feel better. (edges, values, and relationships are probably more important than colour, but that's another essay)
One of the easiest ways to learn about colour mixing, is to do colour matching. DrawMixPaint's style is especially focused on this idea of just (as if it's that simple) putting the right colour in the right place and poof! Painting happens perfectly. And even if that isn't the style you are going for in your own art, if you have ever struggled with milky or muddy colours, do a painting or two in his style and it will solve most if not all your colour problems.
Once you've tried his style, go back to your usual style and see how the colours suddenly behave kindly towards you instead of fighting against you at every stroke of the brush.
The mind-blowing crazy thing I found out from watching this guy mix colours is that, on a modern palette, there are two, not just one, but two different ways to lighten a colour. We can use Titanium white which is blue-leaning, or - and this is the mind-blowing bit - we can add YELLOW. (no hats were hurt in the blowing of this mind). Yellow can't get very dark in value and the yellow paint most of us use when oil painting today, is very, very light in value. Cad Yellow Lemon, Hansa, Azo... all of these are 7-8.5 on the value scale. Much lighter than we think they are.
I'm measuring these values Munsell style where 10 is the ultimate white - aka, the one that doesn't exist - and 0 is the ultimate black which again, is a colour that doesn't really exist. In comparison, Titanium white is probably about 9.5ish.
Next time you reach for white to lighten a colour. Stop. Ask yourself, does it need to be warmer or cooler? Would yellow do the trick?
And that's all well and good, but kind of hard. Isn't there an easier way?
Mixing Dark to Light
I admit it, I'm a mixer. I like to mix a few colours before embarking on a painting. That way I have a starting point that I can adjust as I go along.
When I'm mixing the colours, I start at the darkest colour I can see on my reference. I slowly get lighter, going as far as I can without adding white. I don't even put white on my palette yet.
Then I paint these areas in as smoothly as possible, because we are working with darks and darker midtones smooth texture helps them hide. When I get those more-or-less blocked in, then I'll put the white on my palette and start mixing the lighter colours. Titanium white is one of the more opaque colours and in oil painting, having opaque colours in the lights helps draw attention to the subject.
In watercolours, it used to be quite common to use opaque colours, especially white, to direct focus away from an area. See Turner and Constable's watercolours for some gorgeous examples of how white can make a watercolour painting sing!
This little trick of working without white for as long as I can manage helps keep the shadows pure and stops them from becoming chalky.
But there is an even easier way.
Change your white
Before, we talked about what we see as white being a very light blue. This causes milky chalky looking colours. What if we got rid of that problem altogether? What if we removed the box-standard Titanium white from our palette and replaced it with something kinder?
It's what people did for most of history.
Titanium white (PW6) is a very new pigment. It's very popular. Titanium white is a cheap pigment to produce. Benign to the human painter and most environmental issues as the lead used in the making is very very small and has tiny traces (but enough to get a warning label in California with the dead fish picture on it). It's a long lasting, happy little white. And it looks like a clean, pure white (aka, it's blue) and the opaque quality of this paint makes it even stronger in the mix..
These days we generally learn to paint with Titanium white and since we learned to paint with it, we keep going with it. It's a powerful colour paint and can lighten the value of a colour very quickly. And makes it more blue/cool at the same time.
But it's not the only white available.
Lead white (PW1 - toxic, yellow-leaning, semi-opaque) and Chalk white (PW18 - non-toxic, grey-blue-leaning, so transparent, it's often used as a filler or transparent mediums) are out of fashion these days. Zinc White (PW4 - non-toxic, blue-leaning, semi-transparent) too is out of fashion because it causes issues with the longevity of the painting. It's a fairly new pigment in the paint world too, and is proving unkind to the paintings.
That leaves us with variations of Titanium white. It doesn't have to be the overwhelmingly blue-leaning opaque hog of a pigment. It takes extra science to make that happen.
Different brands have different names, but some of the ones I've tried and been impressed with are Portrait White, Buff Titanium (unbleached titanium), transparent white, and flake white hue (the hue is important here as it means it's not the toxic lead stuff that we need to be extra careful when handling). And these whites make sense. They are all less blue than Titanium white and several are yellow or orange-leaning. Kind of like how our eyes see the world - slightly yellow or orange leaning...I might have to swap out my hat for a thinking cap.
Unless one is working from a poor quality photograph that has the highlights blown, bright blue-whites are unusual in our daily lives. It's often recommended that we first mix our Titanium white with a touch of yellow ochre before painting so we don't get tempted to use it out of the Titanium White tube.
Most of the world just isn't that white.
They give us this powerful paint and then tell us how to make it calmer. Why not skip that step and start with a warm white?
Or we could go a step further and take white off our palette entirely.
In this painting he doesn't use white at all. Just yellow.
My favourte for this kind of thing is Naples yellow as it's a very calm yellow and most modern versions have quite a bit of white added to it already (although the expensive ones might not).
