Depending on the platform you are on, the application palette should automatically be derived from your desktop settings such as KDE or Windows colour schemes and fusion will make use of those instead.

ok, sorry for the missing details.
I'm on Linux (openSuse 13.1) using KDE 4.12 beta, Qt5 self compiled (but it also happens with Qt 5.1.1 from openSuse).
The style in KDE I use is QtCurve. I also checked now my color settings but found nothing strange.

I found the code which parses kdeglobals (QKdeThemePrivate::readKdeSystemPalette()).
I have extracted the color settings of this file and attached it
