Python Tkinter Colorchooser: Effortlessly choose and display colors

Last update on April 25 2025 12:53:22 (UTC/GMT +8 hours)

Write a Python GUI program to create a Colorchooser widget to select a color using tkinter module.

Sample Solution:

Python Code:

import tkinter as tk
from tkinter import colorchooser

def choose_color():
    color = colorchooser.askcolor(title="Select a Color")
    if color[1]:
        selected_color_label.config(text=f"Selected Color: {color[1]}")
        color_frame.config(bg=color[1])

parent = tk.Tk()
parent.title("Colorchooser Example")

# Create a button to open the color chooser dialog
choose_color_button = tk.Button(parent, text="Choose a Color", command=choose_color)
choose_color_button.pack(padx=20, pady=20)

# Create a label to display the selected color
selected_color_label = tk.Label(parent, text="Selected Color:", font=("Helvetica", 10))
selected_color_label.pack()

# Create a frame to display the selected color
color_frame = tk.Frame(parent, width=100, height=50)
color_frame.pack(padx=20, pady=20)

parent.mainloop()

Explanation:

In the exercise above -

Import 'tkinter' as 'tk' and 'colorchooser' for creating GUI components and accessing the color chooser dialog.
Define a function "choose_color()" that opens the color chooser dialog using colorchooser.askcolor(). As soon as a color is selected and the dialog is closed, it returns a tuple containing the color's RGB format and its name. We update the label and frame with the selected color.
Create the main window using tk.Tk() and set its title.
The 'choose_color_button' button will call the "choose_color()" function when clicked.
Create a label named 'selected_color_label' to display the selected color.
Create a frame named 'color_frame' to display the selected color as a background color.
The main event loop, root.mainloop(), starts the Tkinter application.
