Question

I’m having a hard time figuring out where a grey color is coming from, first a picture to illustrate:

As you can see I have drawn 3 arrows which (I know it is a bit hard to see) show the grey outline.

My code goes:

master = Tk()
master.title("Skrå kast")
master.resizable(width = FALSE, height = FALSE)
w = Canvas(master, width=630, height=598, bg="#FFFFFF")
w.grid(row = 1, column = 2)

#...

labelframe = LabelFrame(master, text = "Parametre for affyring", background = '#FFFFFF', bd = 3, font = ("Aeria", "8", "bold"))
labelframe.grid(row = 1, column = 1, ipady = 217, ipadx = 2, padx = 3, pady= 2, sticky = N)

#...

w.create_rectangle(10, 4, 630, 596, fill = "#ffffff", outline = "#000000")
w.create_text(320, 30, text = "Simulering af skud med kugle", fill = "#000000", font = ("Arial", "20", "bold"))

Where on earth is that grey outline coming from?

I suspect it is the labelframe, however I have not been able to find a way to get rid of it. Not even tampering with the paddings work.

That color is almost certainly the background color of the root widget. You can check it pretty easily by doing something like master.configure(background="red") to see if this mystery color becomes red.
