How to change foreground color of a ttk button that is disabled?

Question

When I disable a button the color change automatically to black. This is the code :

from tkinter import *
from tkinter import ttk
root=Tk()

style=ttk.Style()
style.configure('TButton', foreground='red')
bu1=ttk.Button(root, text="Hello world")
bu1.grid(row=0, column=0)

bu2=ttk.Button(root, text="Hello world2")
bu2.grid(row=1, column=0)

bu1.state(['disabled'])
bu2.state(['disabled'])

root.mainloop()

Any help?

Since you are using a ttk button, you can map certain attributes to different button states with the map method of the style object.

For example, to change the colors when the button state is "disabled", you can set the color like this:

style.map(
        "TButton",
        foreground=[("disabled", "black")]
)
