"Color expands a photograph's palette and adds a new level of descriptive information and transparency to the image.  It is more transparent because one is stopped less by the surface -- colour is more like how we see.  It has added description because it shows the colour of light and the colours of a culture or an age."—from the Martha & Gary Hill Library, Paris, France:  Stephen Shore in The Nature of Photographs, Phaidon Press, 2007, p.16
