“The white square is a sign of pure functioning. The white square is a direct impulse for the world. We can understand it as pure functioning as knowledge of oneself in the pure utilitarian perfection of the all-person.

The black square is a sign of economics, economising and reduction.

The black and white squares also draw attention to the extinguishing of colour.

Colour gives way to whiteness.

The Suprematist carrier is the white space and by no means the blue. The colour blue does not give us a true idea of the infinite. It is as if the ray of the gaze were bumping into the celestial vault, unable to break through into infinity. The infinite Suprematist white allows the ray of the gaze to expand without limit.

Black and white in Suprematism are energies which reveal shapes to us.”
