Kapoor similarly explores the immateriality of pure pigment and color as a spiritual and physical experience, with works like his void sculptures and pigment installations sharing Klein's obsession with color depth and the dissolution of physical boundaries.

Judd's Minimalist furniture and sculptures combine industrial materials like chrome and Plexiglas with bold color fields in functional yet conceptually rigorous objects, directly paralleling Klein's fusion of design, materiality, and pure color expression.

Flavin shared Klein's dedication to a single color or material as a complete conceptual statement, using monochromatic light installations to explore immateriality and the transformative power of color saturating a physical space.
