Margaret Livingstone - Vision and Art
The biology of seeing

forward by David Hubel

“ I am a neurophysiologist. I spend my time investigating why some nerve cells in our visual system are sensitive to color whereas others are not. In the process I have become particularly interested in something that artist have been aware of for a very long time:
that color and luminance (or lightness) carry different kinds of visual information “

“Colors are only symbols; reality is to be found in lightness alone.”
Pablo Picasso
