Re: too much contrast?

If your aim is to meet the current web accessibility standards, I wouldn't
think too much contrast is something to design for. As you noted, WCAG is
very specific about minimums, but say nothing for maximums.

When I was working in an AT center, people who had scotopic sensitivity had
some choices for toning down brightness with onscreen viewing

Colored screen overlays were popular, as well as OS level settings to make
everything that was white another color. Once we learned about that,
everyone in my office had pale green or blue backgrounds in MS Word. It
didnt print out green, but was gentle on the eyes when typing up reports.

There are also a few softwares out there such as f.lux that will change the
color temp of screens. It's not specifically for scotopic sensitivity, but
some may like the options.

As long as what you put out on the web respects the AT that people with
light sensitivity use, you should be fine.
