Ron Cooper is a west-coast based American artist born in 1943 who started his career in the late ’60s in Los Angeles. He currently resides in Taos, New Mexico. By 1973, he had already participated in numerous international solo and group shows with pieces in the permanent collections of the Guggenheim Museum, NY and LACMA. His work was exhibited at the La Jolla Museum of Contemporary Art, La Jolla, California, May 13-July 1, 1973. Cooper's work explores light, reflection, transparency, and color, through the medium of colored fluorescent lights, neon, and glass. In his Separator Variations series the colored fluorescent fixtures, separated by glass, reflect and appear to overlap combining the colors producing a third hue. Most of his pieces, like the Separator Variations series, demonstrate the additive nature of light, (the subtractive result of combining colors of light). His other work included environmental installations and neon focused on the same themes.
