Get in fresh colour (5)
I believe the answer is:
tinge
'colour' is the definition.
(tinge is a kind of colour)
'get in fresh' is the wordplay.
'fresh' indicates an anagram (a fresh re-ordering of the letters).
'get'+'in'='getin'
'getin' is an anagram of 'TINGE'.
(Other definitions for tinge that I've seen before include "A colourful" , "show a bit of colour ?" , "Touch (of colour?)" , "Subdued colour" , "A slight shade of colour" .)
