Well, this problem seems specific to the Abstract set, as I am not aware of any other set that uses bright red for piece coloring. And I don't recall having ever used Abstract in an Interactive Diagram. When I am transforming the main diagram in an article to an interactive one I tend to skip those articles that use Abstract, because there are no anti-aliased images available for that yet. So it seems more efficient to postpone these until there are.
The Ultima Diagram initially is not in Abstract either, and it is only due to the theme buttons that it can be switched to using Abstract. So I don't think there is any problem there, or at worst that the problem is very minor: there might be one or two IDs that I overlooked somewhere on this website, and people viewing those with a new model Kindle would not be able to distinguish the black pieces from the white. This seems unlikely to happen ever, but if it does, they could complain, and we know how to fix it.
