COMPLEMENTARY CONTRAST/CONTRAST OF SATURATION
COMPLEMENTARY CONTRAST: the contrast between 2 colors directly opposite from one another on the color wheel; when placed side by side, these two colors intensify one another. When mixed together, they neutralize one another.
CONTRAST OF SATURATION: the contrast between pure, intense colors and dull, diluted colors
When painted at full intensity with equal proportions the complementary colors may appear harsh, but the contrast will be great. Many paintings based upon the complementary contrast color schemes make use of neutralized tones of the complementary colors in contrast with small portions of the colors at full intensity.
Use the complementary pair that was assigned to you. This will be either: blue/orange; yellow/violet or red/green.
Step 01: Adjust the value level of the two colors to be equal by adding white.
NOTE: This is will lighten the colors and reduce the saturation somewhat, although they will still be relatively pure in hue. The goal is to reduce light/dark contrast in order to maximize the effects of complementary contrast and contrast of saturation.
Step 02: Mix a grey that is equal in value to the two colors.
Step 03: Add this grey in varying proportions to get two chromatic tones for each color. This will result in a total of seven different colors.
Step 04: Assign these colors to the composition to create a perceptual shift in elevation. (a) Use the principle that intense colors come forward in space (advance) and dull colors go back in space (recede). (b) Enhance complementary contrast by placing similar intensities of the two complementary colors next to one another.
