Jules Olitski's *Rake's Progress #4* showcases the artist's mastery of color field painting through luminous layers of acrylic and enamel applied to a Plexiglas surface. The translucent support allows light to interact with the paint in a uniquely dynamic way, creating a sense of depth and radiance that distinguishes the work from his canvas-based pieces. Soft, atmospheric gradations of color drift across the composition, embodying Olitski's ongoing exploration of pure chromatic sensation and painterly abstraction.
