Placed beside each other in a composition, they create contrast, and often, vibration. The property of value distinguishes between the lightness and darkness of a hue. All colors reflect a different quantity of light as well as a different wavelength. It is important to recognize the normal value of a hue. We also refer to intensity as the degree of saturation in a color.
Spectrum hues have the highest intensity.
If the gray is the same value as the original hue, the intensity will change, but not the value. Add complementary hue. The mixture of two hues exactly opposite each other on the color weel such as red green, blue orange, or yellow and violet result in neutral gray or brown. Complementaries present an equal balance of three primaries, a different result than adding neutrals. In these examples we can see how one color beside another changes the character of other colors.
