A ghost from Hades (5)

I believe the answer is:

shade

'a ghost' is the definition.
(I know that ghost can be written as shade)

'from hades' is the wordplay.
'from' indicates anagramming the letters (the anagram comes from the same letters).
'hades' with letters rearranged gives 'SHADE'.

(Other definitions for shade that I've seen before include "remains" , "Colour; protection from sun" , "Hue" , "Partial or comparative darkness" , "Slight colour difference" .)

I've seen this clue in The Globe and Mail.
