Like some car windows (6)
I believe the answer is:
tinted
'like some car windows' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for tinted that I've seen before include "Slightly coloured as hair may be" , "'Coloured, shaded (6)'" , "Lightly coloured" , "Coloured slightly, spectacles or windscreens" , "Faintly coloured" .)
