I actually have a patch sitting around that starts to do this -- I never 
got around to proposing it to the list.  Parsing CSS-style color names 
is certainly flexible, but given that 99.9% of uses are going to be rgb 
or rgba, I'd agree that [r, g, b] or [r, g, b, a] should be accepted as 
colors (in the range of 0.0 to 1.0) wherever colors are accepted in the 
canvas API..
