In the 1960s, Klein Blue, also known as International Klein Blue (IKB), transformed the relationship between art, design, and spatial perception. Created by the French artist Yves Klein, Klein Blue emerged as one of the most iconic colors of the decade, symbolizing modernity, experimentation, and a break from tradition. Its intense, saturated, and vibrant tone goes beyond decorative use and becomes a powerful visual statement.

During the 1960s, designers and architects actively used Klein Blue to enhance new plastic forms, innovative materials, and Pop aesthetics. They applied this bold blue to emphasize volumes, create striking contrasts with white and orange, and highlight futuristic furniture with soft, sculptural lines. In an era defined by technological optimism and space-age culture, Klein Blue represented depth, infinity, and avant-garde design.
