Can I use rgb in tkinter?

No, tkinter does not support RGB, but you can write a small helper function to remedy this:

Maybe something like this, where the argument rgb must be a valid rgb code represented as a tuple of integers.

import tkinter as tkdef _from_rgb(rgb):    """translates an rgb tuple of int to a tkinter friendly color code    """    return "#%02x%02x%02x" % rgb   root = tk.Tk()root.configure(bg=_from_rgb((0, 10, 255))) root.mainloop()

If you find it more readable, you can also use fstrings to achieve the exact same result:

def _from_rgb(rgb):    """translates an rgb tuple of int to a tkinter friendly color code    """    r, g, b = rgb    return f'#{r:02x}{g:02x}{b:02x}'

Note that the colorsys module from the Python standard library can help translate from HSV, HLS, and YIQ color systems

def rgbtohex(r,g,b):    return f'#{r:02x}{g:02x}{b:02x}'print(rgbtohex(r=255, g=255, b=255))

Hope this helps some of you

Sorry for not answering correctly, I didn't think it through properly. Now that I have seen your comment @Mike-SMT, I've improved it

from tkinter import *import randomimport timewindow = Tk()window.title("Random colours")colours = ["black",           "cyan",           "magenta",           "red",           "blue",           "gray"                 ]bgColour = window.configure(background = random.choice(colours))window.update()time.sleep(1)bgColour1 = window.configure(background = random.choice(colours))window.mainloop()

Have fun with this, you can get creative and do things like making this into a forever changing background colour, or making a sequence. There are so many different colours on Tkinter that you can use, so you can manually change each colour after every few seconds if you really want. Another thing I forgot to mention previously, you can't use a time.sleep() option as Mike said, but it will work if you use a ".update()" line of code, as shown above.
