I generally use an off-white. Most of my prints are warm, often lightly sepia toned and a plain white matt looks "wrong". I think cold toned prints look better with a plain white matt. I've never tried black. I'll have to get some next time I am buying to see how it looks.

I suspect a dark, warm colour might look good but it would shout "gimmick!" to me. Probably I'm just too conservative...


Cheers, Bob.
