They really want to get accessibility as good as they can (and in fact several of the current site schemes are available because people had accessibility issues with other ones) so it's def. worth asking. I'll put an official site suggestion in for a black-and-white tropospherical type scheme if that's okay with you.

And I know how annoying lynx is; I've been stuck using it on LJ ever since they stopped properly supporting my browser and I had to turn off javascript. I think DW's lynx scheme is slightly more functional than LJ's, but still not great.
