Now you can use Folder Color in Ubuntu MATE 14.10 too!
Caja & Folder Color
Just run these commands into a Terminal:
sudo add-apt-repository ppa:costales/folder-color
sudo apt-get update
sudo apt-get install python-caja gir1.2-caja caja libgtk2.0-bin folder-color-caja
If your Ubuntu is 32bits:
sudo cp /usr/lib/i386-linux-gnu/girepository-1.0/Caja-2.0.typelib /usr/lib/girepository-1.0/
If your Ubuntu is 64bits:
sudo cp /usr/lib/x86\_64-linux-gnu/girepository-1.0/Caja-2.0.typelib /usr/lib/girepository-1.0/
Finally, restart your file browser:
caja -q
PS: If you're using the Nemo file browser (Usually with Cinnamon) see how to install here.
