   VGA uses 6 bits for each of red, green and blue, so you have a palette of
2^(6*3)=256K colours to choose from.  Depending on the display mode you're
using, you may have up to 256 colours on the screen at a time.  Note, however,
that since there are only 64 values for each of the three primaries, and
that gray is produced by an equal value in each primary, you can only get
64-level grayscale.
