Dull, without lustre (5)

Ross

I believe the answer is:

matte

(Other definitions for matte that I've seen before include "Mask used in film; ET mat (anag.)" , "Mask used to block out areas of the image in filming" , "Mask used to add an image in front of camera" , "Dull, flat" , "A dull finish" .)

I've seen this clue in the Sydney Morning Herald.
