On a backbone router with many interfaces route show scrolls for quite
some time and it is difficult to see at a glance what is going on.
Colour coding is an obvious improvement.
The following diff sets the background colour to green for up routes
and black for down routes.
The default route has yellow text colour (because 10BASE5 yellow
cable), reject routes red and blackhole routes black text colour.
Host routes are underlined, multicast routes blink and multipath
routes blink fast.
I believe the colours are intuitively obvious so no need to document
the meaning.
OK?

I'm not entirely sure you are real.
