I like the stock ubuntu icon theme but the orange arrows not so much.
so i mixed the Faenza theme with the Ubuntu mono light theme for personal use. I uploaded this theme so other users can also use it.
The only change are the arrows, the are now black inside Nautilus and Firefox etc. thats it ;-)
To make things clear, I did not make this theme you can find the original theme inside the Ubuntu installation and the Faenza theme here:
Copy the icons into
/usr/share/icons. (need root access)
Tested on Ubuntu 12.04
