Beige look-alike (4)
I believe the answer is:
ecru
'beige look-alike' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ecru that I've seen before include "Unbleached-linen colour" , "Raw linen colour" , "off-white" , "Light fawn colour" , "not whiter than white" .)
