This is a complete (I think) dark color palette for the Qt 5 Fusion theme, as well as a nice style sheet for the tool tips that make them blend better with the rest of the theme. To have immediate effect, be sure to put this in your main function before showing the parent window. Child windows should automatically inherit the palette unless you …

Qt 5 Dark Fusion Palette

    qApp->setStyle(QStyleFactory::create("Fusion"));

    QPalette darkPalette;
    darkPalette.setColor(QPalette::Window, QColor(53,53,53));
    darkPalette.setColor(QPalette::WindowText, Qt::white);
    darkPalette.setColor(QPalette::Base, QColor(25,25,25));
    darkPalette.setColor(QPalette::AlternateBase, QColor(53,53,53));
    darkPalette.setColor(QPalette::ToolTipBase, Qt::white);
    darkPalette.setColor(QPalette::ToolTipText, Qt::white);
    darkPalette.setColor(QPalette::Text, Qt::white);
    darkPalette.setColor(QPalette::Button, QColor(53,53,53));
    darkPalette.setColor(QPalette::ButtonText, Qt::white);
    darkPalette.setColor(QPalette::BrightText, Qt::red);
    darkPalette.setColor(QPalette::Link, QColor(42, 130, 218));

    darkPalette.setColor(QPalette::Highlight, QColor(42, 130, 218));
    darkPalette.setColor(QPalette::HighlightedText, Qt::black);
    
    qApp->setPalette(darkPalette);

    qApp->setStyleSheet("QToolTip { color: #ffffff; background-color: #2a82da; border: 1px solid white; }");

Wow! This is great stuff. The only thing that isn't perfect out of the box is that deactivated buttons look the same as clickable ones. Otherwise - love it.

darkPalette.setColor(QPalette::ToolTipBase, Qt::white);
darkPalette.setColor(QPalette::ToolTipText, Qt::white);

Why do you set both as white and then add qApp->setStyleSheet("QToolTip { color: #ffffff; background-color: #2a82da; border: 1px solid white; }"); ?

Very cool! One thing I spotted was that tab control are a bit black-on-black... Would be nice if the tabs themselves could be shaded a bit differently.
