1. A modulator of light comprising:

  • a substrate;

    a plurality of modulation elements formed on the substrate each modulation element defining an interference cavity for causing interference modulation of the light to produce a color condition when in a quiescent state, wherein the modulation element is of at least two types each having a different color condition when in the quiescent state, which color condition is a result of a spatial configuration of the modulation element.
