LGBTQ* Slogan and Flag History
The Rainbow/Pride Flag creation is credited to Gilbert Baker; it debuted at the San Francisco Gay and Lesbian Freedom Day Parade in 1978.
The original flag had eight stripes:
pink (sexuality) — red (life) —orange (healing) — yellow (sunlight) — green (nature) — turquoise (magic) — indigo/blue (serenity) — violet (spirit)
Pink and turquoise have since been dropped.
That makes sense, because the sex and magic are totally gone from the mainstream Gay Rights movement.
