Q: Why are some colors in the less partials not externalized to variables.less?

Created by: artificialhoney

tried to customize bootstrap bundled with https://github.com/seyhunak/twitter-bootstrap-rails. By simply overwriting the colors in variables.less i cannot achieve a harmonic result (e.g nav-list divider), due to some colors, hardcoded in the other lesses.

Analyzing those partials i got :

Found 26 colors

So there are 26 colors hardcoded overall, some of them also appear in variables.less.

I think it would be an advantage to also have them externalized.
