Yeah, but the color isn't really information there... so it's
not exactly an acessibility problem.

Yeah, that might be some other spots, but what I mean is that in
most cases GNOME is colorblind-friendly.

Yeah... I was talking to Carlos about this, and there's one important
thing about it, usually the people who would use the colorblind filters
would not need the zooming, so it probably don't make sense to make its
management gnome-mag-oriented.

Probably just creating a gnome-applet that does what test/control-client
(inside gnome-mag source) does, but being colorblind-oriented would be
enough.
