[Chimera-users] Color blending on ribbons

Hi, I wondered if there is any easy way to blend colors from one residue to the next on a ribbon chain (as in the rainbow facility.) I want to be able to precisely define where this takes place (ie whenever I switch from one color to another) - more specifically I am coloring different regions of a superimposed pair to show where is aligned and where is not, and the drastic switch from one color to the next would definitely look better more blended.
