Equinox Themes are both good-looking, stable and light themes related to others, in my opinion. I prefer equinox themes with different variations. It uses faenza icon set which is popular in ubuntu world. It has ppa support also which is big advantage for being updated. The theme also uses mono icons for gnome panel which is very suitable with white panels mostly.

For further details, you can visit gnome-look page.

Open the terminal and paste the following lines;


sudo add-apt-repository ppa:tiheum/equinox
sudo apt-get update
sudo apt-get install gtk2-engines-equinox equinox-theme equinox-ubuntu-theme
