or use hsv2rgb macro (is that correct spellig ?) 

btw.
how about ne future - types of colors interpolating :
colors_rgb
colors_hsv ?

i.e.

gradient color_map{[0 rgb <1,0,0>][1 rgb <0,1,0>] colors_rgb}
will give : red dirty-red dirty-yellow dirty-green green

gradient color_map{[0 rgb <1,0,0>][1 rgb <0,1,0>] colors_hsv}
will give : red red-yellow yellow yellow-green green

I will write try to implement this futre, do You think it would be usefull 
?
