PyQt5 Label – Adding Color effect

Last Updated : 28 Apr, 2025

In this article we will see how we can add color effect to the label by default there is no color effect to the label although we can create color effect for the label. Color effect is not like background color it is more like of colored filters we use on pictures, below is the representation of how label with color effect looks like

In order to do this we have to do the following - 1. Create a label 2. Set geometry to the label 3. Create a QGraphicsColorizeEffect object 4. Add this object to the label with the help of setGraphicsEffect method

Syntax :

# creating a color effect
color_effect = QGraphicsColorizeEffect()

# adding color effect to the label
label.setGraphicsEffect(color_effect)

Below is the implementation

Python3

# 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):
        super().__init__()

        # making background color cyan
        self.setStyleSheet("background : cyan;")

        # setting title
        self.setWindowTitle("Python ")

        # setting geometry
        self.setGeometry(100, 100, 600, 400)

        # calling method
        self.UiComponents()

        # showing all the widgets
        self.show()

    # method for widgets
    def UiComponents(self):

        # creating label
        label = QLabel("Label", self)

        # setting geometry to the label
        label.setGeometry(200, 100, 150, 60)

        # setting alignment to the label
        label.setAlignment(Qt.AlignCenter)

        # creating a color effect
        color_effect = QGraphicsColorizeEffect()

        # adding color effect to the label
        label.setGraphicsEffect(color_effect)


# create pyqt5 app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()

# start the app
sys.exit(App.exec())
