Brown ant maybe (3)
I believe the answer is:
tan
'brown' is the definition.
(tan is a kind of brown)
'ant maybe' is the wordplay.
'maybe' indicates an anagram.
'ant' anagrammed gives 'TAN'.
(Other definitions for tan that I've seen before include "Sun-baked colour" , "Brown colour acquired from sun" , "Bark!" , "Lightish brown colour" , "Skin colour after exposure to ultraviolet rays" .)
