Subject: iproute2: color output should assume dark background

Hello,

Debian is now building iproute2 with color output on by default. This brings attention to the fact that iproute2 defaults to a color palette suitable for light backgrounds.

The COLORFGBG environment variable, if present and correctly set would select a dark background. However COLORFGBG is neither ubiquitous nor standard. It wouldn't typically be present in a non-graphical vt, nor is it presnet in XFCE and many other desktop environments.

Dark backgrounds seem to be the more common default, and it seems many people stick to that in actual use.

The dark blue used by the ip command for IPv6 addresses is particularly hard to read on a dark background. It's really important for the ip command to provide basic usability e.g. when manually bringing up networking at the console in an emergency. I find that fiddling with extra details just to disable or improve the colors would be an unwelcome nuisance in such situations, but the Debian maintainer outright refuses to revert this change, without explanation or discussion.

Instead the maintainer suggested I submit a patch upstream, which I will do. I've never contributed here before, so your patience and guidance would be very highly appreciated.

Thanks,
