Colour scheme and furnishings (5)
I believe the answer is:
decor
'colour scheme and furnishings' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for decor that I've seen before include "Interior colour scheme and furnishing" , "stage background" , "(Room) design" , "Scheme of interior furnishings" , "Internal ornamentation" .)
