The following three examples include using a simplified image and using four color ways: an achromatic palette of 7 tones from white to black; three analogous hues with the option of mixing in a bit of black, white, or gray; and two sets of tetradic color relationships. Tetradic color schemes employ four colors arranged into two complementary pairs.
What can you do when you limit your palette? Students were asked to take a high contrast image, preferably one of their own, and transfer it twice. The finished works were rendered using a set of three analogous colors (colors that appear next to each other on the color wheel) plus black, white, or gray. The other palette consisted of a pair of complementary colors, allowing them to intermix the complements, or add black, white, or gray. Getting your values right works every time!
