In the
United States, some hippies refer to themselves as "Rainbows," a name derived from their tie-dyed T-shirts, and for some, from their participation in the hippie group, "Rainbow Family of Living Light". Since the early 1970s, the Rainbows meet informally at Rainbow Gatherings on U.S. National Forest Land as well as internationally. "Peace, love, harmony, freedom, and community" is their motto.
