Grant delivered dye (3)
I believe the answer is:
hue
'dye' is the definition.
(huing is a kind of dyeing)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for hue that I've seen before include "complexion" , "Tint, shade" , "General outburst of alarm or protest - . . . and cry" , "Tinge" , "Colour or tint" .)
