Abstract
Providing color management includes receiving measurements of the intensity of colors. A light source generates light beams to yield the colors, where the light beams are generated in accordance to image data to create an image. A target color value is established. A duty cycle sequence operable to control the light source is selected in accordance with the measurements and the target color value. Current levels for currents provided to the light source are selected in accordance with the duty cycle sequence and the target color value.
