Colour screen (5)

I believe the answer is:

shade

This clue is a double definition.

'colour' is the first definition.
(shade is a kind of colour)

'screen' is the second definition.
(thesaurus)

(Other definitions for shade that I've seen before include "Hue" , "Nuance" , "remains" , "See 15" , "Colour; slight amount" .)

I've seen this clue in The Independent.
