But Noë's more interested in color as an ecological property -- a feature of the way light and surfaces interact. Like Goethë, he believes that color is fluid, changing, open to interpretation. We think of it as stable, but it's not. It can look one way under one light, one way under another, different when you turn it different ways or notice a new highlight. By his estimation, "It’s not... intrinsic to the surface of the leaf that it is green. It's greenness is in the way it behaves in relation to lighting."
