Colourful, free cutting that is with bouquet (10)
I believe the answer is:
iridescent
'colourful' is the definition.
(similar in meaning)
'free cutting that is with bouquet' is the wordplay.
'free' becomes 'rid' (to be free of something is to be rid of it).
'cutting' means one lot of letters goes inside another (some letters cut their way into a word).
'that is' becomes 'ie' (short for Latin 'id est', 'that is').
'with' says to put letters next to each other.
'bouquet' becomes 'scent' (the scent of a wine).
'rid' inserted into 'ie' is 'iride'.
'iride'+'scent'='IRIDESCENT'
(Other definitions for iridescent that I've seen before include "Sparkling" , "shot" , "Glittering with changing colours" , "changing colour" , "Shimmering with rainbow colours (anag of 1 across, 9 and 23)" .)
