Sandy hue (4)
I believe the answer is:
ecru
'sandy hue' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ecru that I've seen before include "not whiter than white" , "Greyish white" , "Strange cure for a colour" , "off-white" , "Colour of unbleached linen" .)
