Colour supplement? (8)

I believe the answer is:

magazine

(Other definitions for magazine that I've seen before include "Ammunition store; publication" , "Storehouse for weapons" , "Slug container" , "Journal, periodical" , "Periodic paperback publication" .)

I've seen this clue in The Guardian.
