Tan-colored (5)
I believe the answer is:
brown
This clue is a double definition.
'tan' is the first definition.
(I've seen this before)
'colored' is the second definition.
(similar in meaning)
(Other definitions for brown that I've seen before include "Kind of sweetener" , "Capability" , "It is used for wrapping" , "Colour of toast" , "Labour PM, b. 1951" .)
