Right tint applied in small amount (11)
I believe the answer is:
entitlement
'right' is the definition.
(entitlement is a kind of right)
'tint applied in small amount' is the wordplay.
'applied' is an anagram indicator.
'in' means one lot of letters goes inside another.
'small amount' becomes 'element' (I've seen this before).
'tint' anagrammed gives 'ntit'.
'ntit' placed within 'element' is 'ENTITLEMENT'.
(Other definitions for entitlement that I've seen before include "amount" , "Right (to receive something)" , "One's due" .)
