In this article we will see how we can get color effect object of the label by default there is no color effect to the label although we can create color effect then add it to the label with the help of setGraphicsEffect method.

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
5. Get the opacity object with the help of graphicsEffect method

Note : This object have same properties of the original object

Syntax :

# creating a color effect
color_effect = QGraphicsColorizeEffect()

# adding color effect to the label

# getting the color object
object = label.graphicsEffect()

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, 600, 400)
        # calling method
        # showing all the widgets
    # 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
        # setting font
        label.setFont(QFont('Arial', 15))
        # setting style sheet of the label
                            "border : 2px solid green;"
                            "background : lightgreen;"
        # creating a color effect
        self.color_effect = QGraphicsColorizeEffect()
        # adding color effect to the label
        # result label
        result = QLabel(self)
        # setting geometry of the result label
        result.setGeometry(200, 200, 300, 30)
        # getting the color object
        object = label.graphicsEffect()
        # setting text to the result label
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
