Shane, looking pale? (5)

I believe the answer is:

ashen

I'm a little stuck... Click here to teach me more about this clue!

'pale?' is the definition.
('ashen' can be a synonym of 'pale')

'shane looking' is the wordplay.
'shane' can be anagrammed to 'ASHEN'.
But, I'm not clear how this is indicated.

Can you help me to learn more?

(Other definitions for ashen that I've seen before include "Pale-faced" , "White-faced" , "Pale (faced)" , "Pale (with shock/illness)" , "Visibly shocked" .)

I've seen this clue in the Evening Standard.
