CSS for visually impaired users

Hi all

I'm currently collecting some stylessheets to include in the CSS-Control 
module. As a start I think these would be suitable (I'll adapt them for 
Konquerors needs).

http://www.w3.org/StyleSheets/Core/preview

I don't think the copyright is a problem, is it?

Apart from these fancy ones I would also like to include CSS for people with 
color blindness, etc. We do not support Aural CSS but I think CSS with bright 
contrast/different colors could be helpful. I'm not an expert on this topic 
and unfortunately I've not been able to find any.

Any links/ideas?

Andreas
