OK thanks, I was not expecting a QPalette to work better than stylesheet (isn't it handled the same way at the end?), but I will try it. I was not expecting a simple color change to be an extensive customization.
This is for a color-proofing imaging software where dark backgrounds gives better eye sensitivity than light ones, especially on potentially very bright monitors. QStyle rewriting is an option, but at high cost, so any simpler solution is welcome. I've read your post here: https://blog.qt.digia.com/blog/2012/10/30/cleaning-up-styles-in-qt5-and-adding-fusion/ It seems that fusion it well color-customizable and platform-independent, since I do not need any fanciness, this may be a good solution.
