Fruit; colour (6)
I believe the answer is:
orange
I believe this clue is a double definition.
'fruit' is the first definition.
(I know that Orange is a type of fruit)
'colour' is the second definition.
(I know that orange is a colour)
(Other definitions for orange that I've seen before include "An ogre (anag.)" , "Colour of Northern Ireland unionism" , "Round fruit (6)" , "One's pipped" , "shade" .)
