Following the DOMA ruling, Facebook launched its latest emoji, a rainbow to signify “pride.”
As you see above, click on the smiley-face image below your status-update box, and then click the “feeling” drop-down menu. You should now see the option to select a rainbow icon under the “feeling” drop-down menu. If you do not see it right away, type in “pride” right after “feeling”, and it’ll magically appear.
A Facebook representative confirmed to Mashable yesterday that the new icon launched in light of the DOMA decision.
