The COLOR is not mentioned explicitly but it seems to be one rare ones not 
fitting the usual binding scenarion as it is almost the only one that has 
multiple parameters. Can there be multiple bindings ? Now you have:

COLOR [r] [g] [b]

if you translate this into the logic of RFC19 does this mean it would have 
three separate bindings for the colour components (items r, g and b), or 
would it still be a single binding that encompasses all three values (like a 
0xRRGGBB(AA) number) ? This especially gets tricky if we are operating with 
PC256 images, should we as Frank asked even use values, or would some sort of 
mapping be more appropriate ?
