Apple-coloured (6)
I believe the answer is:
russet
I believe this is a double definition.
'apple' is the first definition.
(a russet-coloured apple)
'coloured' is the second definition.
(similar in meaning)
(Other definitions for russet that I've seen before include "Autumnal reddish brown" , "Reddish brown; apple" , "Brown; apple variety" , "Autumn red" , "Brown with a reddish tinge" .)
