Shane, awfully pale (5)
I believe the answer is:
ashen
'pale' is the definition.
('ashen' can be a synonym of 'pale')
'shane awfully' is the wordplay.
'awfully' is an anagram indicator.
'shane' with letters rearranged gives 'ASHEN'.
(Other definitions for ashen that I've seen before include "Very pale, with shock or fear" , "Grey in colour" , "Having gone pale" , "Pale (with shock/illness)" , "White-faced" .)
