The Rainbow flag or Pride flag of the LGBT community (also known as the gay pride flag) is a symbol of LGBT pride and LGBT social movements in use since the 1970s. The colors reflect the diversity of the LGBT community, and the flag is often used as a symbol of gay pride in LGBT rights marches. It originated in the United States, but is now used worldwide. Designed by San Francisco artist Gilbert Baker in 1978, the design has undergone several revisions. As of 2008, the most common variant consists of six stripes, with the colors red, orange, yellow, green, blue, and violet.
