From 1969 to 1974, Chicago presented Atmosphere events in locations across California and the Northwest, ranging from secluded woods and beachfronts to art museums and university campuses. Natural or constructed, the locales were instantly transformed and aestheticized by bursts of colored smoke triggered by the flares. Chicago saw this project as releasing the diaphanous colors of her sculptural Domes to soften and “feminize” the environment. The effect was further emphasized in later versions in which nude women, their bodies painted in intense hues, interacted with plumes of smoke.
