Using a rainbow flag as a symbol of gay pride began in San Francisco, but eventually became common at LGBT rights events worldwide. Also known as the gay pride flag or LGBT pride flag, the colors reflect the diversity of the LGBT community and the spectrum of human sexuality and gender. The rainbow flag is a symbol of lesbian, gay, bisexual, transgender ( LGBT) and queer pride and LGBT social movements.
