Sunbather's goal (3)
I believe the answer is:
tan
'sunbather's goal' 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 "Brown to beat" , "Yellowish brown" , "Get the effect of the sun." , "Catch the sun" , "Lightish brown colour" .)
