Fox::FXColor should really be a Ruby module and not a class; you can't 
create instances of it and use them in any meaningful way. And as you 
already noted, we already have a way to construct color values from the 
red, green and blue (and optionally alpha) components, e.g.

	color = Fox.FXRGB(r, g, b)

or

	color_with_some_alpha = Fox.FXRGBA(r, g, b, a)

It's not clear what advantage a full-blown FXColor class would offer.
