Blonde hue (3)
I believe the answer is:
ash
'blonde hue' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ash that I've seen before include "Timber tree" , "Dusty residue of a fire" , "Knotty - - (Ken Dodd)" , "Powdery residue from fire or cigarette" , "Silvery grey" .)
