Hi!

Is there a way to compute to a given color a darker one on a VGA card (256
color modes preferred)?
E.g., given "white" as input, the algorithm should output "gray" and so on.
Up to now, I'm using an ad-hoc lookup-table, but this approach relies on the
standard palette...

*ANY* ideas welcome,

TNXIA, 
         Kai
