Color Interaction Studies – Continued

This color study will explore color interactions by shifting value in color.


  • Choose one hue as your small, center square color, preferably one that is in middle key. Try to work with this color for the remainder of your studies.
  • Attempt to make this one color appear as two by varying the surrounding color.
  • For each pair choose one background hue and adjust the value by adding white and/or complement.
  • For example:
    • In the first pair (blue) the value is altered by adding white to the left square and the complement to the right square. The center square appears darker on the left and lighter on the right.
    • In the second pair (yellow), the slightly muted yellow on the left and the chromatic gray on the right alter the perceived value of the center square.
    • Work with different surrounding hues, altering the perceived value at all levels of saturation (chromatic grays, muted and prismatic) until you achieve a perceptual difference between center squares. It’s interesting to notice how these two studies look in grayscale.


  • Complete your 2 pairs of color interactions making value adjustments in color (you may have to make several attempts)
  • Come prepared with painted color scraps and paints, brushes, etc for the next experiment.
