These are indeed the ANSI codes for the colours but ANSI
codes only work in an ANSI terminal and GUIs are not
ANSI terminals. Instead they have their own ideas on
colours and you need to use those. They all support
the standard 16 colours used in ANSI however, so in
your case (for Tkinter at least) just use the names
'red', 'yellow', 'blue' and 'green'

> colors = [red, yel, blu, grn]

colors = ['red', 'yellow', 'blue', 'green']

But again that won't work in a GUI, you need to use the GUIs
way of colouring. In Tkinter that's via tags as per my
previous post, reproduced here).

You need to change the loop to iterate over the letters
instead of words and choose the tags at random. But that
should be fairly straightforward.
