Color Contrast

The purpose of this article is to define color contrast in a way that's relevant to photographers. To better understand color we can break it down into 3 separate components: Hue, Saturation and Luminance.

Hue names the color. So a red rose has a red hue, while a yellow shirt has a yellow hue.

Saturation defines the purity of a color. The color can be either high in saturation (e.g. a vivid Red light at a stage performance) or low in saturation (e.g. pastel pink bridesmaids dress).

Luminance describes the relative lightness or darkness of the color. You can have, for example, a bright blue sky or a dark blue shadow. And yes, as we'll discover in subsequent articles, shadows are often blue.
