A shade naive, after courage (6,5)
I believe the answer is:
bottle green
'a shade' is the definition.
(I've seen this before)
'naive after courage' is the wordplay.
'naive' becomes 'green' (similar in meaning).
'after' means one lot of letters go next to another.
'courage' becomes 'bottle' (bottle can mean courage).
'green' after 'bottle' is 'BOTTLE-GREEN'.
(Other definitions for bottle green that I've seen before include "A shade" , "Colour -- to be gentler (anag)" , "Dark virid colour" .)
