Light golden brown (5)
I believe the answer is:
hazel
'light golden brown' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for hazel that I've seen before include "Catkin-bearing shrub" , "Filbert" , "Eye shade - tree" , "Tree; girl's name" , "Tree - greenish-brown" .)
