Change Facebook colour

Color My Facebook

Color My Facebook is an extension (for any web browser) that allows users to change the layout color from the trademark blue. Once you install the application, Color My Facebook will change the blue to pink, but you have the option to choose any color after that. If your friends have the same add-on installed and have changed the color, you will be able to see the color they have chosen, as well.

Color Changer for Facebook

Out of all of the add-ons out there, this Chrome extension is the most popular. Color Changer for Facebook allows you to not only change the color of your Facebook, but customize the top Facebook bar, friend names, and the main headlines, feed texts, and background. It might be more work for some, but if optimal customization is your thing, then this extension might be what you're looking for.

iStyla

iStyla, the creation of a 14-year-old web developer, offers users several themes and presets that can be found on the iStyla Store. Other users that have iStyla can see your themed profile and vice versa. The only thing missing with this extension is the ability to customize.
