Is there any specific reason why the language construct takes something 
fairly simple (this much red, this much green, this much blue) and 
complicates the hell out of it?

Mmmm, I'm wondering how tricky it would be to specify the pastel colours 
(azure, that sort of thing).


I'd be inclined to maintain a look-up table of the "common" colours 
(there'd only be 8-32 depending on what you think of as common).

For the rest, work with divisions of 256, like half green would be:
     128th of 256.
Can this reduce?
     64th of 128.
Can this reduce?
     32th of 64th.
And so on until you arrive at the simplest arrangement. This is missing 
out a lot, but since I'm numerically dyslexic (and getting ready for 
work once I finish my sukiyaki), you'll have to make do with this for 
now. ;-)

Computer video cards understand levels of 0-255, HTML colours (etc) 
understand levels of 0-255, this seems an unnecessarily complicated 
step? <grin>


Best wishes,

Rick.
