Richard Serra (b. 1938)

‘Black is a property, not a quality. In terms of weight, black is heavier, creates a larger volume, holds itself in a more compressed field. […] Since black is the densest colour material, it absorbs and dissipates light to a maximum and thereby changes the artificial as well as the natural light in a given room. A black shape can hold its space and place in relation to a larger volume and alter the mass of that volume readily.’
–Richard Serra
