Hi Ibrahim, I'm not 100% sure why you want to rainbow the highlighted part of your structure, rather than use a single color, or color the rest of the structure dark gray, or make the rest of the structure semi- transparent, or many other possible highlighting schemes. Anyway, there's no way to do it without resorting to (simple) Python. Put the following in a file that ends in ".py": import chimera residues = chimera.selection.currentResidues() residues.sort() for i, r in enumerate(residues): r.highlightNum = i+1 Then select the residues you want highlighted in Chimera. Run the Python script by opening it with the "open" command or with the File-
Open dialog. Then run this Chimera command:

Dear Chimera team,
I wonder if there is a way to color a certain range of residues using rainbow. I tried to use the rainbow command with atom_spec but it applied for the whole chain.
What I want to do is to color part of the structure as a rainbow (from blue-white-red) with an increasing order of residues number. I just wanted to highlight a region of conformational change so the eye can follow which part of the structure has changed dramatically.
Thanks in advance for your help.
Ibrahim
