I assume you mean -u?

Vim thinks your terminal has colour capability, and is
guessing a light background.

It can't guess reliably, so to ensure it thinks you have
a dark background you can tell it with ":set background=dark".
You should see the legibility of the colours improve after
this.

I mean, if you like bugs that will never be fixed ... :-)

To tell Vim that no colours are available:

set t_Co=0

You can add this to your command to invoke Vim:

vim -u NONE -c 'set t_Co=0'
