Raw colour (5)
I believe the answer is:
green
This clue is a double definition.
'raw' is the first definition.
(synonyms)
'colour' is the second definition.
(I know that Green is a type of colour)
(Other definitions for green that I've seen before include "Village space" , "17's colour" , "Gullible" , "Money" , "Unripe; envious" .)
