For the colours like blue and magenta, using \e[34;1m and \e[35;1m would
make it more readable against dark background. And testing with a dark
background right now, that would suffice the other colours are not
problematic to read. (It uses the "bright" version of the two colours
rather than the usual.)

That would be a miniscule change to iproute2 and would resolve the
problem no matter what background is used. I need to test with schemas
like solarized light and dark as well, as they are finicky.
