cbx040,
have got a point,but WPs colour scheme is tame compared to another forum am use [a major uk forum for people with all types of disability]-here's a part of a screen shot of it:
http://img141.imageshack.us/img141/5682/fffqu2.jpgthat forum has so many users who have some sort of disability which is affected by the colour scheme,eg,visual impairment,dyslexia,visual perception problems [part of autism and as,and not] and so on.
one users layout is another users difficulty,and with visual perception being a big part of autism and as-it makes sense to have a few themes installed but maybe there is reason for not having installed any.
if find have got problems on a lot of sites with colours,what about trying a screen reader.
It is such a shame there aren't any other themes installed.
I was looking at the table layout and thought a screen reader would have problems with it.
