VGA uses analog colosr signals to basically allow you to specify colors to the monitor using only a few signals. Red intensity Blue intensity Green intensity Sync The intensity are analog voltages, the higher the voltage, the greater the intensity of that color. You can theorically display an infinite number of colors using this scheme (although graphic card standards and monitor technology limit this. VGA is capable of 262144 colors, but only 16 or 256 (depending on mode) at one time.
