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":
residues = chimera.selection.currentResidues()
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:
rangecolor highlightNum,r min blue mid white max red sel
