Borrowing symbolism from the hippie movement and black civil rights groups, San Francisco artist Gilbert Baker designed the rainbow flag in response to a need for a symbol that could be used year after year. Use of the rainbow flag by the gay community began in 1978 when it first appeared in the San Francisco Gay and Lesbian Freedom Day Parade. The rainbow also plays a part in many myths and stories related to gender and sexuality issues in Greek, Native American, African, and other cultures. The multicultural symbolism of the rainbow is nothing new - Jesse Jackson's Rainbow Coalition also embraces the rainbow as a symbol of that political movement.
The rainbow flag has become the easily-recognized colors of pride for the gay community.
