This section covers the color chooser module in Tkinter.
Tkinter is full of mini libraries that offer new and interesting features, improving the overall look and feel of your Python GUI. One of these many Tkinter Libraries is the Color Chooser.
You can import the askcolor function from the Color Chooser library using the following code.
from tkinter.colorchooser import askcolor
The syntax for the askcolor function is as follows. All parameters on this function or optional. You can assign it a default color and a title, but you can also leave both of these out.
result = askcolor(title = "Tkinter Color Chooser")
The look of this Color Chooser can vary from operating system to operating system, but the general purpose and functionality remains the same.
Color Chooser Example
Below is a standard example of the askcolor function, without the supporting tkinter window.
Any color you pick will return a tuple as it’s value. There are two values contained in this tuple. The first is a RGB representation and the second is a hexadecimal value. We’ll be needing the hexadecimal value for tkinter.
result = askcolor(title = "Tkinter Color Chooser") print(result) print(result) print(result)
We picked a random color using the code above. See it’s output below.
((92.359375, 116.453125, 228.890625), '#5c74e4') (92.359375, 116.453125, 228.890625) #5c74e4
Extra Tkinter Example
Here’s an extra example of the use of the Color Chooser’s askcolor function. This is the kind of example you’ll see in real life, where the user selects a color, and the font color on the GUI changes accordingly.
from tkinter.colorchooser import askcolor def callback(): result = askcolor(title = "Tkinter Color Chooser") label.configure(fg = result) print(result) root = tk.Tk() tk.Button(root, text='Choose Color',command=callback).pack(pady=20) label = tk.Label(root, text = "Color", fg = "black") label.pack() root.geometry('180x160') tk.mainloop()
We’ve run the function, and picked the color blue from the color palette. You can now see that the color of the text in the label has been changed.
