    Description

      QFusionStyle uses the following code to determine the button color:

      QColor buttonColor(const QPalette &pal) const {
    QColor buttonColor = pal.button().color();
    int val = qGray(buttonColor.rgb());
    buttonColor = buttonColor.lighter(100 + qMax(1, (180 - val)/6));
    buttonColor.setHsv(buttonColor.hue(), buttonColor.saturation() * 0.75, buttonColor.value());
    return buttonColor;
}

      The call to QColor::setHsv() applies the default alpha value of 255, instead of inheriting the alpha value from the QPalette.
