Blue material (4)

Ross

I believe the answer is:

smut

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

This is all the clue.

(Other definitions for smut that I've seen before include "(Speck) of dirt" , "Soot, dirt, grit" , "Bit of soot or dirty talk" , "blue material" , "Small flake of dirt" .)

I've seen this clue in The New York Times.
