Brown with a reddish tinge (6)
I believe the answer is:
russet
'brown with a reddish tinge' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for russet that I've seen before include "Brownish-red apple" , "Brown; apple variety" , "Dessert apple" , "Reddish brown; apple" , "Surest type of colour" .)
