Hi Nick, We're glad you like ChimeraX!
You can specify any color palette with "rainbow" (i.e. doesn't have to be a standard ROYGB palette).
Example:
rainbow /a palette darkblue:lightskyblue
With the "rainbow" command "palette" option you can specify a named palette or define it with 2 or more colors. The simple example above uses 2 color names, but you can have more colors, and if they don't have names in ChimeraX, you can use hex codes, RGB, etc. as explained in the help. See

Dear ChimeraX list,
Thanks so much for this amazing software!
I have a kind of obscure question for which I could not find an answer on Google.
I've got the FliPQR-FlhB structure, from here: https://www.rcsb.org/structure/6S3L
This has
5 copies FliP 1 copy FliR 4 copies FliQ 1 copy FlhB
I opened it and am using ribbon view.
I've colored the chains by protein type with these commands:
color /a,b,c,d,e purple color /f red color /g,h,i,j green color /k yellow
Now, I'd like to have each chain shaded from N-terminus to C-terminus, e.g. dark red to light red, or something like that. (I see the rainbow option, but this creates a very complex view if all 11 chains are each an roygbiv rainbow.)
Almost as good, is there a way to easily label the N-terminus and C-terminus of each chain?
Any suggestions!
Thanks so much, Cheers, Nick
