Pale yellow-gray color (4)
I believe the answer is:
ecru
I believe this clue is a double definition.
'pale yellow' is the first definition.
(I've seen this in another clue)
'gray color' is the second definition.
(I know that ecru is a type of gray color)
(Other definitions for ecru that I've seen before include "light beige" , "Find a cure, strangely, in the colour" , "Natural stuff" , "Bleached linen colour" , "Pale, creamy brown" .)
