Omar Rayo (1928-2010) as a Colombian painter, sculptor, caricaturist and plastic artist. He won the 1970 Salón de Artistas Colombianos. Rayo worked with abstract geometry primarily employing black, white and red. He was part of the Op Art movement. Rayo's work shows that geometric art is as much a part of the past as it is of the future. He used traces of the past to discover new ways to present visual and geometric sketches.
