Hi Jane,
I think you just wanted to apply the "heteroatom" color-coding to that residue.  For example, select it and use

menu: Actions… Color.. by heteroatom
or
command: color byhet sel

That will keep the carbons as their current color but use the element color-coding for the others.  Or, you could use "by element"  instead, which will also color the carbons by element (gray).

If I misunderstood your question, you could try asking it again.  I hope this helps,
Elaine
