Best colour for the topcoat? (5)

I believe the answer is:

cream

I'm a little stuck... Click here to teach me more about this clue!

'best' is the definition.
(as in 'the cream of the crop')

I don't understand the rest of the clue.

(Other definitions for cream that I've seen before include "'There are more ways of killing a cat than choking it with ....." , "Best - substitute for shaving soap" , "Elite; off-white" , "Pick - fatty part of milk" , "Dairy product" .)

I've seen this clue in the Evening Standard.
