FT-130404-HRC.png.CROP.original-originalThe Human Rights Campaign (HRC) created an image of a pink equal sign on a red background to signify support for gay marriage as the Supreme Court began meeting to consider the future of same-sex marriage in the U.S. The image was promoted by HRC in a variety of ways, martha-equal-cakeand if your friend group is anything like mine, you probably saw facebook go red around the end of March in 2013.
