Here's the answer to your question.
color green, resn leu (colors all leu green)
color green, resn leu+gly (colors all leu and gly green)
color green, (pept and resn leu) (will color leu of object 'pept' only; useful
when you have multiple objects displayed).
The selection expressions above and examples can be found in the PyMOL manual
Hope that helps.
I was wondering if there is a way to color all of a specific type of amino
acid the same color in a pdb file (i.e. all the Leucines colored green, all
the lysines blue, etc).
