Poetry in colour or vice-versa (8)
I believe the answer is:
reversed
'vice-versa' is the definition.
I can't judge whether this defines the answer.
'poetry in colour' is the wordplay.
'poetry' becomes 'verse' (synonyms).
'in' indicates putting letters inside.
'colour' becomes 'red' (red is a kind of colour).
'verse' put inside 'red' is 'REVERSED'.
'or' is the link.
Can you help me to learn more?
(Other definitions for reversed that I've seen before include "what the answer to the final clue [Send up and down (5)] might be" , "revoked" , "Put backwards" , "Drove car backwards" , "withdrawn" .)
