Bicolor Lessons in Values

4/23/19 Maple Leaf neighborhood

In Shari Blaukopf’s book, Working with Color, I saw many appealing examples of limited color palettes. Shari herself showed examples of the lovely, cohesive paintings she achieves by using only three primaries, and other artists made striking sketches using just one distinctive hue plus black.

Since I often think about using a limited palette to minimize my sketch kit, seeing these examples reignited my interest in trying again, but this time with a specific purpose in mind: helping me see and interpret values.

I tried a similar exercise last year with limited, unrealistic hues, hoping to trick my brain into ignoring the local colors and seeing the values more easily. This time I am using two high-contrast colors only – one warm and one cool. I tried the green and orange sketch first, assigning orange to the lighter values and green to the darker values. Where the value was darkest, I mixed orange and green together.

The orange and green I chose didn’t have high enough contrast for my purpose, so next I chose a red/blue (or more specifically, vermillion and Prussian blue) bicolor editing pencil (above). This time I assigned red to lighter values and blue to darker. These hues had the added benefit of better evoking warm/light and cool/shade. This sketch required playing serious mind games with myself! The truck was actually dark red, so it was very tempting (and natural) to use red to sketch it . . . but squinting at it, I could see that its values were mostly dark except for reflections on top. So I sketched it in blue (partially from memory, since it drove off before I could finish).

Also, the caution diamond in the traffic circle was, of course, bright yellow, and the traffic cone (why was it there? Who knows) was bright orange, and I was so tempted to use the appropriate colors! But in fact, they were in shade, so I tried to hint at their warmer local hues while coloring them mostly blue.

I find it helpful to codify values this way by assigning unrealistic hues to them. Even better, I like the effect of the red and blue used together beyond the purposes of the exercise.

A vintage Mitsubishi editing pencil
Geek note: The red/blue editing pencil is a vintage Mitsubishi. You may recall that I have a particular fondness for bicolor pencils, even though most are not useful to me. This Mitsubishi has strong pigment and is pleasantly soft to use. Its contemporary version has the same cores, as far as I can tell. (A reason to use bicolor pencils always makes me happy!)
