Doesn't Qt already does this? I mean, I notice that Krita (and other KDE4 
apps) flicker from dark to light gray and back whenever it loses and gains 
focus. It is really, really, really annoying, especially for a graphics app 
that whenever the user clicks on a floating dock widget, picks a color in a 
color dialog or opens a filter dialog or even switches to another document 
the surroundings of the image they're working on changes from light to dark. 
Every time that happens, the document seems to change color, too, by virtue 
of the way the human eye works.

(Of course, with other applications it's very annoying too, but it makes good 
graphics applications in KDE4 impossible.)
