Another post that is absolutely false. 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.
