Shade found in pigment, in general (5)
I believe the answer is:
tinge
'shade' is the definition.
(tinge is a kind of shade)
'in pigment in general' is the wordplay.
'in' indicates the answer is hidden within the clue.
'TINGE' can be found hidden inside 'pigment in general'.
'found' is the link.
(Other definitions for tinge that I've seen before include "A shade or a nuance" , "Suffuse" , "A smack" , "Slight amount of colour" , "Touch (of colour?)" .)
