Tints, tones (6)
I believe the answer is:
shades
I believe this clue is a double definition.
'tints' is the first definition.
('shade' can be a synonym of 'tint')
'tones' is the second definition.
('shade' can be a synonym of 'tone')
(Other definitions for shades that I've seen before include "suspicions" , "Sunglasses, colloquially" , "Nuances" , "disguise, sometimes" , "Hip sunglasses or gloomy ghosts" .)
