I believe the answer is:

ashy

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

'pale' is the definition.
(I've seen this before)

I don't understand the remainder of the clue.

(Other definitions for ashy that I've seen before include "Dusty" , "like Cinders" , "resembling cinder track?" , "Like burnt residue" , "Cinders must have been this" .)

I've seen this clue in the Evening Standard.
