Dealing with colour, check an artist like Turner eschews navy (9)
I believe the answer is:
chromatic
'an artist like turner eschews navy' is the definition.
I can't tell whether this defines the answer.
'dealing with colour check' is the wordplay.
I cannot really see how this works, but
'check' could be 'ch' (abbreviation) and 'ch' is found in the answer.
'dealing with' could be 'at' (eg looking at something) and 'at' is located in the answer.
The remaining letters 'romic' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for chromatic that I've seen before include "Trim coach (anag.)" , "colourful?" , "in colours" , "With use of colour" .)
