Color Interaction Studies – Continued

NEXT INTERACTION STUDY: Value in Color : 2 color studies will explore interactions by shifting value in full color.


  • Choose one hue as your small, center square color, preferably one that is in middle key. You will 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 vary the value using different saturation levels.
  • For example:
    • In the first pair (blue) the value is altered by adding white to the left square and black or 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 alter the perceived value and saturation of the center square.
    • Work with different surrounding hues, altering the value at all levels of saturation (achromatic grays, muted and prismatic) until you achieve a perceptual difference between center squares. Notice how these two studies look in grayscale.


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