Sense of taste evident in a sound choice of colours (6)
I believe the answer is:
palate
'sense of taste' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for palate that I've seen before include "having ability to appreciate good food" , "part of trap" , "One may savour" , "A plate (anag.)" , "relish" .)
