I finally found a good documentation on the color codes (and other things) of the Linux console (Bash
in my case). The funny part is, it was right there all the time: man console_codes.
There you'll find a lot of stuff with proper background. Quite handy if you want to do something nice
on the console but don't want to use big libraries like ncurses for it. I found the link in an old
article.
May the color be with you (or your scripts). 🙂
ps.: Here's a short version.
