Bridget Riley's "Carnival" exemplifies her pioneering work in optical abstraction through its dynamic interplay of vibrant colored forms that create an illusion of movement and visual vibration across the paper surface. This screenprint demonstrates Riley's signature technique of using geometric patterns and carefully calibrated color relationships to engage the viewer's perception and induce a sense of rhythmic energy. The work's full margins and execution on wove paper showcase the technical precision characteristic of Riley's practice during her exploration of color and optical effects in the 1960s and beyond.
