Facebook has launched a tool that lets users show their support of marriage equality. Facebook’s "Celebrate Pride" tool wasannounced by co-founder and chief executive Mark Zuckerberg. The tool was launched shortly after the U.S. Supreme Court ruled that same-sex marriage is now considered a fundamental constitutional right guaranteed under the 14th Amendment.

By visiting the “Celebrate Pride” tool on Facebook, you will see a preview of your profile picture with a rainbow filter. If you click “use as profile picture,” then your existing profile photo will be uploaded with the rainbow filter that is similar to Zuckerberg’s photo above.

“We still have much more to do to achieve full equality for everyone in our community, but we are moving in the right direction.” he told.
