| | Color Context |
 | | Complementary colors are pairs of colors, diametrically opposite on a color circle: as seen in Newton’s color circle, red and green, and blue and yellow. |
 | | This color shift is what we would expect in a chroma contrast, and it may happen because the chroma of 80 is enough to make the yellow appear duller than the turquoise, even though the lightness of the two colors is the same. |
 | | According to Rood, the shift color (the color in the central square, which can be expected to shift) should be unsaturated and mid valued, and it should be surrounded by a single strongly saturated color. |
