Set Background Color on Website Proofs

[#1]

When adding a URL for proofing a website, it would be beneficial if we could specify a background color. There are times that there's transparency on blocks, which results in just showing the dark gray UI from Proof HQ. It would be great if we could specify a color to be used as the background.

This needs to be universal for all proofs.

Yes! Yes! I just uploaded proofs for black business cards – can't see the edge of cards. I would suggest neutral grey, as used in photography, at the very least. Or a user activated choice between white, grey, black for all proofs.
