Daniel, I suppose the first question is “why does it need to be red?” Anything that animates is going to catch the user’s attention anyway, so I don’t see any great harm in keying the background to the theme.
That said, since gtk+ 2.10, haven’t themes been able to support additional named colours, to highlight things like ‘errors’ and ‘warnings’ where appropriate? So shouldn’t Clearlooks and the other themes be providing these now? Or did we just never decide what the standard list of named colours should be? :/
IBM announced last week that they’re scaling back their efforts on open source accessibility projects. As one of the major contributors to this area over the past few years, they’ll certainly leave a bit of a hole if the community doesn’t rally round to help fill it. There’s often a perception that accessibility is “one of those things that Sun or IBM will take care of”, but this announcement (along with Bill Haneman, the “accessibility name” that GNOME folks may be most familiar with, recently moving on from Sun) should make it clear that it’s not the case, nor was it ever meant to be.
The Ubuntu accessibility team are doing a great job now too, but now would be a good time for anyone who writes GNOME software to re-acquaint themselves with the basic accessibility requirements and testing tools, to help spread the load somewhat.Check out this thread on gnome-accessibility-list for more reaction and thoughts on continuing to move open source accessibility forward.
