How do i change the colour of a border in tkinter

I have looked at other solutions which recommended using highlightcolor and highlightbackground, however these did not work.

excercises_button = Button(canvas, width=327, height=150, image=dumbell_img,borderwidth=4, relief="ridge", bg = "gray55", command = Excercises)
canvas_excercises_button = canvas.create_window(168, 724, window=excercises_button)

I would like the border of this button to be orange.

This is what it currently looks like: https://i.sstatic.net/3QX8X.png

Here is an example of how one can have a kind of border created by using a frame and a button.

import tkinter as tkroot = tk.Tk()frame = tk.Frame(root, highlightbackground="orange", highlightcolor="orange", highlightthickness=4, bd=0)
frame.grid(row=0, column=0)
# adding weights so the button is center on the frame.
frame.columnconfigure(0, weight=1)
frame.rowconfigure(0, weight=1)btn = tk.Button(frame,text="test", borderwidth=4, relief="ridge", bg = "gray55").grid(row=0, column=0)
root.mainloop()
