Ok, got you. And e.g. KATE should use these if we are able to get these 
features completed.

The traffic light metaphor might not work for people with disabilities 
(i.e. full or partial color blindness), which is why the roles are 
supposed to be customizable.

Anyway as you seem to have figured out, this is not tinting, this is 
full blown new color roles, or at least that was the latest plan AFAIK.

Ok, I see what you're saying, but that's harder. By 'pixmap-using 
styles' I take it you are thinking of e.g. Keramik? That's different 
because they are using their own pixmaps, not ones set by the user 
globally, i.e. they come from the style not Qt, which is what I was 
thinking about.

Not to say this isn't a real issue, by any means, just that I don't 
consider it as high a priority ATM. But feel free to help out :-).

Anyway this is drifting a bit off the topic of the original thread, I 
would prefer to resume this later in a new thread.
