pyqt color picker

PyQt5 supports a color picker known as QColorDialog. This dialog is a typical dialog that you would see in a paint or graphics program.

To get a color from PyQt5 dialog simply call:

color = QColorDialog.getColor()

PyQt5 color dialog example
The example below opens a QColorDialog after clicking the button (qpushbutton), and returns the selected color.

import sys
from PyQt5.QtWidgets import QApplication, QWidget, QPushButton, QColorDialog
from PyQt5.QtGui import QIcon
from PyQt5.QtCore import pyqtSlot
from PyQt5.QtGui import QColor

class App(QWidget):

    def __init__(self):
        super().__init__()
        self.title = 'PyQt5 color dialog - pythonspot.com'
        self.left = 10
        self.top = 10
        self.width = 320
        self.height = 200
        self.initUI()
    
    def initUI(self):
        self.setWindowTitle(self.title)
        self.setGeometry(self.left, self.top, self.width, self.height)

        button = QPushButton('Open color dialog', self)
        button.setToolTip('Opens color dialog')
        button.move(10,10)
        button.clicked.connect(self.on_click)
    
        self.show()

    @pyqtSlot()
    def on_click(self):
        openColorDialog()

    def openColorDialog(self):
        color = QColorDialog.getColor()

        if color.isValid():
            print(color.name())

if __name__ == '__main__':
    app = QApplication(sys.argv)
    ex = App()
    sys.exit(app.exec_())
