Pink jumper has good taste (6)
I believe the answer is:
salmon
'pink' is the definition.
(salmon pink is a kind of pink)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for salmon that I've seen before include "Fish (often smoked)" , "Large fish with pink flesh" , "See 3" , "'No alms, oddly, for this fish (6)'" , "Migratory fish" .)
