As of Wednesday, the HRC's original image had been shared 66,000 times. There's no clear metric for how many Facebook users adopted the pink and red logo as their profile pictures, but it quickly became ubiquitous enough to turn many people's Facebook feeds a new shade of crimson-as well inspire a host of spin-off profile pictures, including an equals sign made from bacon strips, an equals sign made from two mustaches, and a Bert and Ernie-approved logo, among others.
The special occasion was the Supreme Court's discussions on California's Proposition 8 and the Defense of Marriage Act, which began on Tuesday. On Monday, HRC replaced its Facebook profile photo and the campaign's regular logo-a yellow 'equals' sign inside a navy-blue square-on its website with a magenta-stripe, red-background interpretation of the same design.
