Google the team behind Gmail has just released 31 brand new themes. Even with these new themes Gmail keeps its very nice and easy to use style, but makes it look even better while doing it.
I have chosen some of my favorites you can see them below. To change your gmail theme all you have to do is go to the “Settings” tab and then click the “Themes” tab.
Have fun finding your favorite theme. Also make sure you comment and tell us whats your favorite!
