Pigment, colour (3)
I believe the answer is:
hue
I believe this clue is a double definition.
'pigment' is the first definition.
(I know that pigment is a more specific form of hue)
'colour' is the second definition.
(a hue is a colour or complexion)
(Other definitions for hue that I've seen before include "Tint, shade" , "Delicate shade" , "Shade, aspect; Vietnam port" , "General hubbub - . . . and cry" , "Cast" .)
