[PyMOL] Coloring different carbons differently

[Полина К. <kor...@gm...>]

Hello, I’m new to PyMOL and I need your help. I want to color different carbons in molecule differently: 1 color - carbon at the beginning of a chain, 2 color - carbon in the middle and 3 color - carbon at the end of the chain. I need to do this for a few molecules. Is there a command to do that? I tried to create different objects and color them in needed colors, but maybe there is a simpler way. 
Thank you in advance.
