Like the following?
import Tkinter
def toggle_color(c):
if c.cget("bg") == "red":
new_color = "green"
else:
new_color = "red"
c.configure(bg = new_color)
root = Tkinter.Tk()
c1 = Tkinter.Canvas(root, bg = "red")
c2 = Tkinter.Canvas(root, bg = "red")
c1.bind("<Button-1>", lambda event: toggle_color(c2))
c2.bind("<Button-1>", lambda event: toggle_color(c1))
c1.pack()
c2.pack()
root.mainloop()
