The Yellow and Blue Equal sign is a logo of the Human Rights Campaign (HRC). The Human Rights Campaign advocates equal rights and opportunities for the United States LGBT (Lesbian, Gay, Bisexual, Transgender) community. The group currently has over 1 million members. The Human Rights Campaign has recently become well known for its advocating of gay marriage, which is currently very controversial in the United States.
The HRC has recently replaced the Yellow and Blue Equal sign logo with an updated Red and Pink Equal sign.
