Originally devised by artist Gilbert Baker, Lynn Segerblom, James McNamara and other activists, the design underwent several revisions after its debut in 1978, and continues to inspire variations. Using a rainbow flag as a symbol of gay pride began in San Francisco, California, 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.
