Okay. It occurs to me that "Attention" could also be used e.g. by 
KSnapshot when drawing the window highlight, or to highlight the rects 
of DOM elements in an HTML DOM browser (e.g. Firefox's DOM Inspector; 
don't know if Konqueror has something similar or not). So there are a 
few use cases.

So unless someone either a) has a better idea, or b) convinces me this 
would be a horrible mistake ;-), I think I will add AttentionColor to 
KColorScheme::DecorationRole for KDE 4.4. I will plan that it will use 
NegativeText by default if the color is not specified in the scheme. I 
will also plan to update all shipped schemes to include this new color.

I'd appreciate also if anyone from -usability has any comments.
