Duchamp's painted chessmen.

There's an age-old debate in the Chess world over whether Black or White is the "superior" colour. Because White makes the first move, White wins an overwhelming percentage of the time. But what if both sides were Grandmasters? Would there still be a colour advantage, or would every game end in a stalemate? The Surrealist artist Marcel Duchamp found his own way to break free of this philosophical "gray area." In 1920, he invented a colour version of his favorite board game in an attempt to turn Chess into an artistic activity.

Duchamp's colour choices weren't arbitrary. Indeed, as Duchamp expert Francis Naumann points out, the colour of each piece served as a "continuous visual reminder of its movement and strategic power." Duchamp's two Rooks were light blue and dark blue. The Bishops were light and dark yellow. As the Queen is a combination of the Rook and Bishop (in terms of power and movement), she blended blue and yellow to form light and dark green. The Knights, sharing no characteristics with other chessmen, were light and dark red. Kings were white and black, and pawns were also white and black. {Via}
