A shade inexperienced, pursuing courage (6,5)
I believe the answer is:
bottle green
'a shade' is the definition.
(I have seen 'A shade' mean 'bottle green' so perhaps 'shade' could also mean 'bottle green')
'inexperienced pursuing courage' is the wordplay.
'inexperienced' becomes 'green' (similar in meaning).
'pursuing' 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 "Colour -- to be gentler (anag)" , "A shade" , "Dark virid colour" .)
