QSlider color

[Captain Haddock]

In the example below when I set the slider value, the slider bar below the indicator appears orange. How can I set it to a different color?

import sys
from PyQt6 import QtWidgets, QtCore


class MainWindow(QtWidgets.QMainWindow):

    def __init__(self):
        super().__init__()
        self.setFixedWidth(400)
        self.setFixedHeight(400)
        self.setStyleSheet("background-color: silver")

        slider = QtWidgets.QSlider(QtCore.Qt.Orientation.Vertical)
        slider.setFixedHeight(400)
        slider.setValue(50)

        self.layout().addWidget(slider)


if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)
    ex = MainWindow()
    ex.show()
    sys.exit(app.exec())

Try setting the stylesheet on the slider.
I think per https://doc.qt.io/qt-6/stylesheet-examples.html#customizing-qslider you need to select the ::groove?
