Since Paris was attacked on Friday night, an outpouring of grief and mourning has taken over social media.

Now, people are filtering their Facebook photos with an overlay of blue, white, and red — the colors of the French flag.

It's similar to Facebook's Celebrate Pride filter, a rainbow overlay that was created for Pride month but became even more ubiquitous when the Supreme Court's decision on gay marriage was handed down.

But it's a little more difficult to get. Currently, Facebook hasn't released an easy URL or link to find the overlay function. Instead, you have to be friends with someone who's already used the filter, and click a "Try It" under their photo.

But there's a way to do it if none of your friends have yet. Keep scrolling to see.
