256 Colors to RGB conversion?

Hi!

Is there a standard array or chart that gives the conversions between
the standard 256 color chart for Basic and their equivalent three RGB
cube values. Or is it a simple mathematical conversion? Thanks.

256 Colors to RGB conversion?

Yes, its easy. Well, actually it isn't a math function - you just get the
value
with INP this is the way

OUT &H3C7,ColorValue
Red = Inp(&h3C9)
Green = Inp(&h3C9)
Blue = Inp(&h3C9)

It is very important to first set the color value and then get RED then
GREEN and then BLUE values in RIGHT ORDER
