OK here
hi !
try to connect to you ramp a 'hsv to rgb' node, then directly control the color value of this node ...
that's all of i think (or eventually i can send you the hsv2rgb algorythm, if so, send me an email)
hope this helps

You can also call the hsvToRgb function or whatever it is called, look it up on the online help. That will convert it for you in MEL....
