Black is unlike any other colour, because blackness can be defined. The black that reflects the least light is the blackest. The reddest red or the bluest blue are a matter of perception, but black is absolute.

If the perception of light is seeing, then black is the colour of invisibility. In space we have observed the ultimate black, a black hole. A total absence of light.

Black is the colour of subtlety, of silhouette and shadow. It is the sensitivity to perceive more than is visible. Black is an introspective colour, the colour of darkness and night.

We choose black for formal occasions. Black is a colour of dignity. It is worn by judges, a colour of fairness, because it is not dyed by any other colour. Black is a stoic and spiritual colour. A colour of modesty and austerity.

Black is timeless. Black is the colour of eternity.
