ButtonColor Withbg/fgAttributes
Tkinter Button widget has attributes bg and fg to set the background and foreground colors. We could assign colors to bg and fg when we initialize the Button object, and change Tkinter Button color with configure method or assign new values to bg and fg keys.
Set Tkinter Button Color
import tkinter as tk
class Test:
def __init__(self):
self.root = tk.Tk()
self.root.geometry("250x100")
self.buttonA = tk.Button(self.root, text="Color", bg="blue", fg="red")
self.buttonB = tk.Button(
self.root, text="Click to change color", bg="gray", fg="purple"
)
self.buttonA.pack(side=tk.LEFT)
self.buttonB.pack(side=tk.RIGHT)
self.root.mainloop()
app = Test()
You could also replace bg with background, fg with foreground to set the Tkinter Button background and foreground color.
import tkinter as tk
class Test:
def __init__(self):
self.root = tk.Tk()
self.root.geometry("250x100")
self.buttonA = tk.Button(
self.root, text="Color", background="blue", foreground="red"
)
self.buttonB = tk.Button(
self.root,
text="Click to change color",
background="gray",
foreground="purple",
)
self.buttonA.pack(side=tk.LEFT)
self.buttonB.pack(side=tk.RIGHT)
self.root.mainloop()
app = Test()
Change Tkinter Button Color With configure Method
After the Tkinter Button widget is created, we could change its color by using the configure method.
import tkinter as tk
class Test:
def __init__(self):
self.root = tk.Tk()
self.root.geometry("250x100")
self.buttonA = tk.Button(self.root, text="Color", bg="blue", fg="red")
self.buttonB = tk.Button(
self.root, text="Click to change color", command=self.changeColor
)
self.buttonA.pack(side=tk.LEFT)
self.buttonB.pack(side=tk.RIGHT)
self.root.mainloop()
def changeColor(self):
self.buttonA.configure(bg="yellow")
app = Test()
self.buttonA.configure(bg="yellow")
It configures the background or equally bg to be yellow.
Change Tkinter Button Color With bg/fg Attributes
bg and fg are keys of Tkinter Button widget object dictionary, therefore, we could change the Tkinter Button color by assigning new values of these keys.
import tkinter as tk
class Test:
def __init__(self):
self.root = tk.Tk()
self.root.geometry("250x100")
self.buttonA = tk.Button(self.root, text="Color", bg="blue", fg="red")
self.buttonB = tk.Button(
self.root, text="Click to change color", command=self.changeColor
)
self.buttonA.pack(side=tk.LEFT)
self.buttonB.pack(side=tk.RIGHT)
self.root.mainloop()
def changeColor(self):
self.buttonA["bg"] = "gray"
self.buttonA["fg"] = "cyan"
app = Test()
