You can find the info about the background images and high contrast mode here:
That was amazingly useful.
I went to my Universal Access settings (Mac) and experimented, both by cranking up the contrast and by switching black/white. My main site* came through pretty well overall. In one place the muted color-coding got lost-- but that was nonessential Added Value anyway. And negative photographs of rats look very weird indeed. But the background color is light enough to go to white, which is obviously the biggest concern.
Odd quirk is that my own desktop color, which I picked for its restfulness, becomes painfully garish at high contrast.
* Looking at an art-studio site with display settings geared toward low visual acuity seemed pretty pointless ;) And the Test Site is designed to look horrible anyway.
