Color akin to khaki (3)
I believe the answer is:
tan
'color akin to khaki' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for tan that I've seen before include "Yellow-brown colour" , "Acquire a sunburn" , "Process" , "Turn dark in sun" , "Make hide into leather - nicely brown" .)
