Yves Klein made a blue unlike any other. He worked with chemists to find a way to keep the color pure, untouched by light or time. The result was International Klein Blue (IKB)—deep, rich, and endless. He figured out how to make a color hold its raw, unfiltered intensity on canvas.


Yves Klein was obsessed with blue. To him, it was the purest and most spiritual color—deeper than the sky, beyond material existence. He believed colors had emotional and philosophical weight, and blue, for him, was the color of the void, of freedom, of the absolute.
