Hi Hena - 

You can type the following commands in the command line of the pymol graphics window, one at a time.

color red, ss h
color yellow, ss s
color white, ss l+''

If you don't mind the loops being green, you could also use the first preset under the Color menu for your object.

[C] > by ss > helix sheet loop (choose the colors you want)

Hope that helps,
Jared

Hi,

Sorry, I forgot to mention that, I have only C-alpha coordinates of 60 chains in one pdb file.

I have 60 identical chains. Each chain is about 140 residues. Residues from 10-36 is helix and residues from 50-56 is beta sheet. I want to prepare a cartoon diagram displaying helix and sheet in red and yellow color respectively and the rest part(loop) in white. I need to do this for all 60 chains in diagram. Can someone help me? what commands I can use for this?
