colour mixing pallet idea (Re: Getting about)

[Emanuele Tamponi]

That's more or less what I'm working on currently (if I've understood 
correctly)...

Anyway, no one of the Color Spaces you proposed are suitable to do what 
we want in the color palette. I'm working on a "Painterly Color Space" 
that will make very realistic mixing, will give you the possibility of 
handle lights, and so on.
