Monday Morning Art School: the color of Spring (part 1)

It’s time to assemble the proper pigments to paint beautiful greens this spring.
Fog over Whiteface Mountain, by Carol L. Douglas.
If March didn’t exactly come in like a lamb this year, it at least came in like a sheep. Don’t be fooled. Some of our most brutal winter storms have been known to happen in March. Walking to church, I pondered the depleted state of our woodpile. I wasn’t the only person thinking on these lines. My pal Naomi told me she was going home to move wood “while the ground is still frozen.”
That doesn’t mean that color is not peeping through here and there. The days are growing longer. We may see snowdrops and winter aconite appearing along granite foundations this week. Back in western New York, two witch hazels ought to be blooming, planted by me.
Spring arrives in a host of rich colors, and we’ll discuss that next week. But we must start with the predominant color, which is green. In my own yard, the green moss on the stone wall and my shed roof are the only visible cues that the season is changing. They tell me that growth and warmth are happening under the surface.

Michael Wilcox published a famous watercolor pigment guide called Blue and Yellow Don’t Make Green. Most of what it tells you can now be found on the internet, but it’s where I first got the idea to add back the banned black.
His point was that there are many routes to the same destination, and that to really mix colors, you need to understand what pigments you’re using, not work from trade names for colors. Consider sap green, for example—a staple of many plein air painters’ toolkit. It’s really a convenience mix made of a phthalo blue and some kind of yellow. The same is true of Hooker’s Green.
Mixed greens, in oils.
The single-pigment (‘true’) greens available are chromium oxide green, viridian, and cobalt green. Chromium oxide green is a lovely, heavy, natural green. Unfortunately, it outweighs everything it’s mixed with. Viridian and cobalt green are lovely, but expensive. Beware viridian hue—it’s just another phthalo in disguise. Any other greens you buy in a tube are just variations of those pigments, or convenience mixes.
To make a whole range of beautiful greens, make sure you have the following pigments in your toolkit. Since they’re all-around useful colors, they make a lot more sense than carrying several greens.

  • Black
  • Ultramarine blue
  • Prussian (or phthalo) blue
  • Hansa (or Cadmium lemon) yellow light
  • Diarylide (“Indian”) yellow
  • Yellow ochre

The rookie error of landscape painting is to make all your greens using the same basic color, modulating lighter or darker for highlights and shadows. You’ll have much more life in your trees if you know all the different ways you can get to leafy green.

In fact, the best way to navigate the colors of foliage is to avoid greens out of a tube altogether. A system of paired primaries gives you more options, avoiding the acidity of phthalo, the weight of chromium oxide green, or the soul-sucking darkness of sap green.
In my experience, bad paint mixing causes paintings to go wrong faster than anything else. Constantly over-daubing to modulate the paint color distorts the original drawing and makes a grey mush. If you’re confident of the color, you can apply it fast and accurately.

I make my greens on a matrix, which I’ve shown you both mixed and on a chart. After mixing greens according to the chart, you can then experiment with modulating your resulting greens with tints (meaning a mix of white and a color). The specific tints are unimportant, but the most useful one for landscape is a mix of white, ultramarine and quinacridone violet, making a pale lavender. It is great for atmospheric perspective.
Note that blue/black pigments are much stronger than the yellows. You need about half the amount of blue or black as you do yellow.

Monday Morning Art School: the need for green

A fast, easy route to mixing plausible summer greens.

Overlooking Lake Champlain, by Carol L. Douglas. Every green in this painting came from the matrix below. And, yes, there’s a scrape in it. It tumbled off a bluff.

The need for green came early to class this year, paradoxically because it’s been cold this spring. There’s little green peeping out in nature, even here on the coast.
Last week in class we worked on salvaging failed paintings. That meant pulling out work from summers past. Most of them included some greens, so we had to mix a green chart.
A basic mixing chart for greens, made by my friend and student Victoria Brzustowicz.
We are only weeks away from painting greens again, in all their light, airy delicacy. Even now, the osier and willows have red and yellow in their branches. By June, we will be wrapped in a blanket of immature foliage ranging in color from pale emerald to pink. It’s a good time to brush up on some color theory.
By August, the color will have settled into a deeper, more uniform tone. The only way to navigate this is to avoid greens out of a tube. A system of paired primaries gives you more options, avoiding the acidity of phthalo green, the weight of chromium oxide green, or the soul-sucking darkness of sap green.
If you look carefully at supposedly-uniform foliate, you will see patches where the color leans toward khaki, yellow, teal, violet and orange. They are what gives life to greens, just as accidental tones give life to human skin.
Michael Wilcox published a watercolor pigment guide called Blue and Yellow Don’t Make Green. Of course they do, but his point was that there are many routes to the same destination. One of the most useful landscape greens is black and cadmium lemon or Hansa yellow. Of all the greens I mix, this and ultramarine with yellow ochre are the two I use the most.

In my experience, bad paint mixing causes paintings to go wrong faster than anything else. Constantly over-daubing to modulate the paint color distorts the original drawing and makes a grey mush. If you’re confident of the color, you can apply it fast and accurately.

Above is the matrix of greens I’ve used for almost twenty years. The range of results is infinite. It depends on the proportions you choose and the brand of paint you use. However, blue/black pigments are always much stronger than their yellow mates. In any mixture, you need about half the amount of blue or black as you do yellow. This has nothing to do with color theory. It’s because darker pigments have more staining power than do lighter pigments.
Victoria Brzustowicz made this color chart based on my workshop palette. Here is a printable PDF.I crossed out the red on the chart because, while I do use it in the studio, in most field painting it’s unnecessary.
Once you’ve finished mixing that matrix, it’s time to tie it to the bigger palette. I encourage students to arrange their paints as above because:
  • It’s efficient;
  • It allows you to mix without thinking;
  • It encourages you to use the full color range in every painting;
  • It prevents the beginner’s error of modulating with white or black;

You can modulate your greens using tints of your other colors. For atmospheric greens, modulate with blues and violets. For warm, lighter greens, modulate with warmer tones.

Above is a photograph I took several summers ago. Your mission is to use the green chart I’ve made and mix tones similar to the different greens in the photo. If you get the mixing right, painting this scene will be a snap.
