[blunte]

I see the white on black ok for a few moments, but soon my eyes can't see anything (or rather, can't discern shapes and text and such).

The worst are websites with white text on black backgrounds. Arstechnica used to do this, and I was unable to read more than a paragraph or two. Then when I would leave and go back to normal sites, I would have all kinds of weird ghost blocks in my vision (character sized).
