When we had a seminar on accessibility, one of my friends here at
the University (who is color deficient) mentioned that until a week or
two before the meeting, he didn't realize that MS Word underlined
words in red and grammatical errors in green (when those options are turned

Another example along the same vein that we discussed is when form
validators change
the color of the text on the form to a certain color (i.e. red) and say that
"fields in
red must be completed" - if someone can't distinguish red for some reason,
how can
they know that the form field is required?

I can't speak for how accurate it is, but at
there is a mechanism to test how your site would look to individuals with
color vision deficiences.

Someone contacted me via my web site and asked if I could give any examples
of how colour blindness affects people in their work - not just web sites,
but office and industrial equipment etc. Is there anyone here who can
provide her with some practical examples?
If so, please contact Ingeborg Marie Dehs Thomas at immelie@hotmail.com.
