For Angela Beloian: In Technicolor, the Boulder-based artist created a body of sharp-looking paintings and screen prints that riffed on minimalism, abstract surrealism, psychedelic art and op art simultaneously. Using flowing hard-edged lines, Beloian created interlocking shapes that are filled in by shifting shades of color that overlap. And what marvelous colors she used. The relationship between them suggested the illusion of light and shadow, lending these utterly simple compositions an unexpected three-dimensionality. The Beloians looked very 1960s-'70s retro, like they had come right off the set of a Star Trek episode. But if the artist's aesthetic sensibility recalls the past, her methods are thoroughly up to date: Her preliminary studies were done on her iPhone.
