Chromatic nuances (5)
I believe the answer is:
tones
'chromatic nuances' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for tones that I've seen before include "Shades" , "Told about the silly ass" , "Tints of colour" , "Notes, characters" , "Qualities of colour, music or speech" .)
