Nuanced (6)
I believe the answer is:
subtle
'nuanced' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for subtle that I've seen before include "Delicate, with fine nuances" , "Discriminatory" , "Capable of making fine distinctions" , "Delicate and understated" , "Not 'in your face'" .)
