Cherry-red colour (6)
I believe the answer is:
cerise
I believe this is a double definition.
'cherry' is the first definition.
(synonyms)
'red colour' is the second definition.
(I've seen this before)
(Other definitions for cerise that I've seen before include "Reddish-pink colour" , "Light purplish red" , "Deep red colour" , "Shade of red" , "Light clear red" .)
