Sorry, but as already mentioned in this bug, I disagree with this
request, as the output is_much_ clearer with colors. Those who don't
want this, can just trivially disable it, just like with networkctl
and others. The default should provide the maximum usability. Even
with a simple 2 IFs case, due to the density of textual information
reported by these commands, color-highlighting helps tremendously to
given prominence to the important information, so that they jump up to
the eye:

This is even more true when there are many interfaces on a system.
