Tkinter canvas colors win32

[Markus]

Hi,

within a Tkinter Canvas I want to draw lines with
canvas.create_line
using different colors.
I used the Tkinter color table or the #123456 notation but only the
very basic colors like "red", "blue", "black", "green" appear.
Most of the colors don't work, no line is on my screen.

For example when I replace "black" with "beige" no line appears.

Anybody knows where the problem is?

Thanks for any comments,

Markus
