Bounce card and wb card

[JFeinbergPhotography]

I was thinking the other day, why not have a bounce card that also serves as a white balance card. Notice I did not say grey card, because it would not work as effectively as a white-colored card would.

Anyway, I've done some searching and haven't found anything. Is there such a thing?

I think most bounce cards, are a bright white stock - that probably use optical brighteners which pull the white away from true neutral - not by much.

I've never seen one, but it would "do" in a pinch.
