Abstract
A system and method for calibrating the color balance of a video camera according to a non-standard photographic color temperature. The systems and methods incorporate a plurality of pigments, namely subtractive primary colors (yellow, cyan, magenta), that each may be utilized as a reference to adjust the color balance of a video camera. Each respective pigment is designed to replace the color white or gray as a reference to adjust the color balance so that the camera can capture the natural color of a light source according to a non-standard photographic color temperature (i.e., white).
