A representation of colors and their complements.
Complementary Colors
Red, green, and blue can be thought of as complementary colors to cyan, magenta, and yellow. These colors cancel each other out when combined in equal amounts. Similarly, adding a small amount of one color reduces its complement by that amount.

Contrast refers to the difference between the lightest light and the darkest dark in the image. A low contrast value indicates that the difference between dark shades and light shades is not very great. A high value indicates a great difference between dark and light shades.
