Isabelle Collin Dufresne, French actress (born 1935)

Isabelle Collin Dufresne, known professionally as Ultra Violet, was a French-American artist, actress, and writer.

As a Warhol superstar she appeared in several of his underground films. Beyond her work in film, she was an active participant in the 1960s and 1970s avant-garde art scene, collaborating with other notable artists and later documenting her experiences in memoirs that chronicled life at Warhol's Factory and her interactions with the era’s leading cultural figures.
