And, that also applies, if provision for coloured text is commented out, in

There's nothing in .bashrc which controls the terminal's interpretation
of color escape sequences. Or in bash, anywhere.
It's entirely between the terminal, and the application which generates
the color sequences. The shell is not involved.
The closest the shell comes to being involved is if you try to trick the
application into thinking it's on a different kind of terminal, by
changing the TERM variable. This rarely works out well, except in
very specific circumstances -- the most notable being "I'm ssh-ing to
a system that doesn't know about my terminal type".
As I've already tested today, it sure as hell doesn't work for apt(8).
Excerpt from .bashrc file:
