This code is available:

from PyQt5.Qt import * class Example(QWidget): def __init__(self, parent=None): super(Example, self).__init__(parent) self.initUi() self.b.clicked.connect(self.chooseColor) def initUi(self): self.setStyleSheet('background : #000221;') self.mainLayout = QVBoxLayout() self.b = QPushButton('Color') self.b.setStyleSheet('color : #000000; background : rgb(255, 255, 255)') self.mainLayout.addWidget(self.b) self.setLayout(self.mainLayout) def chooseColor(self): dialog = QColorDialog(self) dialog.setStyleSheet('background : #7c7c7c;') if dialog.exec_(): red, green, blue, _ = dialog.currentColor().getRgb() self.b.setStyleSheet('background : {0}; font-size: 12pt; font-weight: 530; color: rgb({1}, {2}, {3});'.format(dialog.currentColor().name(), 255 - red, 255 - green, 255 - blue)) if __name__ == '__main__': app = QApplication([]) c = Example() c.show() app.exec()

However, when the style changes, the Ok and Cancel buttons remain with the color of the parent widget. How to fix it?

remove self from QColorDialog(self) i.e. change to QColorDialog()

 from PyQt5.Qt import * class Example(QWidget): def __init__(self, parent=None): super(Example, self).__init__(parent) self.initUi() self.b.clicked.connect(self.chooseColor) def initUi(self): self.setStyleSheet('background : #000221;') self.mainLayout = QVBoxLayout() self.b = QPushButton('Color') self.b.setStyleSheet('color : #000000; background : rgb(255, 255, 255)') self.mainLayout.addWidget(self.b) self.setLayout(self.mainLayout) def chooseColor(self): dialog = QColorDialog() dialog.setStyleSheet('background : #7c7c7c;') if dialog.exec_(): red, green, blue, _ = dialog.currentColor().getRgb() self.b.setStyleSheet('background : {0}; font-size: 12pt; font-weight: 530; color: rgb({1}, {2}, {3});'.format(dialog.currentColor().name(), 255 - red, 255 - green, 255 - blue)) if __name__ == '__main__': app = QApplication([]) c = Example() c.show() app.exec()
