Abstract

A graphics color table uses a 5 bit per color Digital-to-Analog Converter (DAC) which provides 32 levels of intensity for each color gun. To drive the highest color intensity to the video screen a "1F' hex value would be loaded and to drive no intensity for a particular color, a "00' hex value would be loaded. An 8 bit per color DAC provides 256 levels of intensity for each color gun. To drive the highest color intensity to the video screen, an "FF" hex value would be loaded, and to drive no intensity for a particular color, a "00" hex value would be loaded.
