Grant sound and colour (3)
I believe the answer is:
hue
'colour' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for hue that I've seen before include "Tinge" , "red or black, say" , "Tone, shade" , "Tint, shade" , "appearance" .)
