I'm trying to add some color to my git configuration and I want to know what color names are available on the terminal. 

* I only want to use colors by name so it's easier for others to understand
* I don't want to add any new colors - I just want to select from the predefined names
* I would like a solution that works for all distros, but primarily Debian
* It would be nice to see the color that the name indicates

Many [online references](http://www.graphviz.org/doc/info/colors.html) often talk about color names that are not defined on my system, so I just need a way to see what my default options are.
