I think maybe you have been watching too much television.  Color
television resolution is actually pretty bad (something like 320 lines
of resolution).  With a color lookup table, a 640*480*256color display
can simulate a 640*480*16million color display.  On a good monitor
(for instance on my AppleColor monitor), the resolution is
approximately 4 times that of a good color television.  When I view 4
GIF pictures it looks like a 4-channel television screen.
