That's true; I was making the point that different colour models should be
supported rather than advocating a particular syntax.

What exactly would you mean the COLOUR (a/or COLOR) element to do? Define
a name which can then be used by BGCOLOR etc.?

(although possible) become tricky to do intuitively for most people.
Probably the best possible would be to convert from the model to RGB and
then filter that through the user's preferences.
