Creating a custom color picker in Python with Tkinter

Python Tkinter Custom Widgets and Themes: Exercise-10 with Solution

Write a Python program to create a custom color picker widget that allows users to select colors from a custom color palette using Tkinter.

Sample Solution:

Python Code:

import tkinter as tk
from tkinter import colorchooser

class CustomColorPicker:
    def __init__(self, root):
        self.root = root
        self.root.title("Custom Color Picker")

        # Custom color palette
        self.colors = ["#FF0000", "#00FF00", "#0000FF", "#FFFF00", "#FF00FF", "#00FFFF"]

        # Create buttons for each color
        self.color_buttons = []
        for color in self.colors:
            button = tk.Button(root, bg=color, width=4, height=2, command=lambda c=color: self.pick_color(c))
            button.pack(side=tk.LEFT, padx=5, pady=5)
            self.color_buttons.append(button)

    def pick_color(self, color):
        chosen_color = colorchooser.askcolor(initialcolor=color, parent=self.root, title="Select Color")
        if chosen_color[1]:
            print(f"Selected color: {chosen_color[1]}")

if __name__ == "__main__":
    root = tk.Tk()
    app = CustomColorPicker(root)
    root.mainloop()

Explanation:

In the exercise above -

• Create a CustomColorPicker class to manage custom color pickers.
• Define a custom color palette as a list of color codes (self.colors).
• Create buttons for each color in the custom palette and assign background colors accordingly.
• When a color button is clicked, the "pick_color()" method is called, which opens a color selection dialog using colorchooser.askcolor. On the console, the selected color is displayed.

Output:

Selected color: #00ff00
Selected color: #d70428
Selected color: #0000ff
