Delicate shade (6)
I believe the answer is:
pastel
'delicate shade' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for pastel that I've seen before include "Delicate and pale in colour" , "Crayon used in art" , "Pale or light colors" , "Crayon - pale colour" , "Outmoded" .)
