Heavenly shade (3,4)
I believe the answer is:
sky blue
'heavenly shade' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for sky blue that I've seen before include "clear as day" , "Seeing this, one may be looking up" , "Pale colour -- buy elks (anag)" , "Heavenly shade" , "Shade (seen above?)" .)
