> KDE can already generate a Gtk+ theme that fits to the current KDE colour

> Some people with limited vision need light text on a dark background and
> very large font and icon sizes. Setting only the background colour and the
> font would not be enough (e.g. a black frame on a black background is
> invisible). Both KDE and GNOME provide themes for some groups of partially
> sighted users, but usability tests have shown them all to be very buggy.
> We are currently working on a complete solution for this for KDE4 and it
> would make a lot of sense to cooperate with other toolkits here.
> Unfortunately GNOME and KDE use completely different approaches for colour
> configuration. In KDE the user can select colours. In GNOME this is coded
> into the themes, which makes it imposssible for the majority of partially
> sighted users to select the exact colours they are comfortable with.
> It requires some thought to find a good solution. I am cc'ing this to the
> FSG Accessibility workgroup so that we can work on it. If other people wish
> to forward it to the Portland list as well, then this is fine by me, as
> long as all suggested solutions are reviewed by FSG Accessiiblity.
