In this article we will see how we can done the color in the QColorDialog widget. This closes the dialog and sets its result code to r. The finished signal will be emitted, if r is QDialog::Accepted or QDialog::Rejected, the accepted or the rejected signals will also be emitted, respectively.

In order to do this we use done method with the QColorDialog object

Syntax : dialog.done(1)

Argument : It takes integer as argument if 0 is passed it will reject the color if 1 is passed it will accept the color

Return : It returns None

Below is the implementation

# importing libraries
from PyQt5.QtWidgets import * 
from PyQt5 import QtCore, QtGui
from PyQt5.QtGui import * 
from PyQt5.QtCore import * 
import sys
class Window(QMainWindow):
    def __init__(self):
        # setting title
        self.setWindowTitle("Python ")
        # setting geometry
        self.setGeometry(100, 100, 500, 400)
        # calling method
        # showing all the widgets
    # method for components
    def UiComponents(self):
        # creating a QColorDialog object
        dialog = QColorDialog(self)
        # setting current color to the dialog
        # making color done
        # executing the dialog
        # dialog.exec_()
        # creating label
        label = QLabel("GeeksforGeeks", self)
        # setting geometry to the label
        label.setGeometry(100, 100, 300, 80)
        # making label multi line
        # setting stylesheet of the label
                            "border : 5px solid black;"
        # getting the selected color
        color = dialog.selectedColor()
        # setting graphic effect to the label
        graphic = QGraphicsColorizeEffect(self)
        # setting color to the graphic
        # setting graphic to the label
        # setting text to the label
        label.setText("Accepted Color : " + str(color))
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app

Output :

In this implementation we didn’t execute the color dialog because we set the current color and accept the color programmatically will make it selected color instead of white which is default by calling the done method
