Interaction of Color Example 6 (Subtraction of Color)

The small rectangles in the middle of each large rectangle seem to be alike, but are actually different (each is the same as one of the two stripes to the side). This is an example of making two very different colors look alike through "subtraction of color". In other words, how to get rid of too much light or dark in a color, or too much hue, as the green or yellow.
