All white. Indefinite Storage.

I will say the backings are nice and thick. The issue is that these backings should have been bigger for New Comics. They are the same size as the comic. For protection there should be at least 1/8" on all four sides. The other major issue is when they come pre-packaged the boards are nice and flat. The moment you take them out, there is a curvature to them. This curvature will not fix itself over time even in the bag. This will result in damage to said comic. Average boards that are much thinner than these are more resilient to bending than these.

Great backing boards, nice and sturdy and acid free. Perfect for storing and maintaining your collection!
