I believe the answer is:

ochre

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

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

I can't explain the rest of the clue.

(Other definitions for ochre that I've seen before include "paint type" , "Orange" , "Pigment made from clay and iron oxide" , "Pale brownish-yellow colour or pigment" , "Buff" .)

I've seen this clue in the Irish Times.
