Blonde shade (3)
I believe the answer is:
ash
'blonde shade' 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 "Hardwood" , "What's left after burning" , "Knotty - - (Ken Dodd)" , "Grey-barked tree" , "Burnt material; tree" .)
