This article by scholar Kim Biel in Lapham’s Quarterly is a fascinating and well-researched rumination on the ever-fascinating subject of color, ranging from painting to photography and back to the natural world: "New Look, Same Great Look"
The article begins:
“Color is among the most challenging aspects of our experience to describe. Spectrophotometers and colorimeters can quantify light waves, yet their measurements have little impact on our feeling for color. As the philosopher Zeno Vendler put it, “Vincent van Gogh loved the color yellow—and certainly not because of its wavelength.” Color is infamous for its variability in language and perception. How can we know that what we are seeing is the same as what someone else sees? How can we separate what we are seeing from the thing itself? Or, as Ludwig Wittgenstein asked in his Remarks on Colour, “Where do we draw the line here between logic and experience?” In the Remarks, written the year before his death in 1951, the philosopher’s thoughts about color invariably lead back to the study of philosophy. What things are knowable? How are they known? What can be determined through philosophical reasoning? Wittgenstein reflected, “Colors are a stimulus to philosophizing.”
