I love the Ubuntu Ambiance theme; however, it is rigid in its colors and does not adapt to user preferences.
So, I modified it so that it does adapt its colors to my mood. I also made a few other modifications for my taste, like smaller buttons, thinner titlebar, etc. Hence, Ambiance-Fine.
Overall, I did this for myself but I thought I'd share ;) See if you like it!
PS: Big thanks Canonical, Inc., who still owns all rights on the theme.
