With nothing colourless, bouquet's full of colour (10)
I believe the answer is:
opalescent
'full of colour' is the definition.
'with nothing colourless bouquet's' is the wordplay.
'with nothing' becomes 'o' (I've seen this in other clues).
'colourless' becomes 'pale' (similar in meaning).
'bouquet' becomes 'scent' (the scent of a wine).
'o'+'pale'+'scent'='OPALESCENT'
(Other definitions for opalescent that I've seen before include "shimmering" , "Shot" , "Sparkling" .)
