Tint; blush (6)
I believe the answer is:
colour
I believe this clue is a double definition.
'tint' is the first definition.
(I know that tint is a more specific form of the action colour)
'blush' is the second definition.
(I know that blush is a more specific form of the action colour)
(Other definitions for colour that I've seen before include "Red or green, say" , "'Tinge, hue (6)'" , "Quality that results from light reflection" , "Blue or green, say" , "Influence" .)
