We CAN perceive UV light: "...An illustration of how ultraviolet appears is provided by the Impressionist painter Claude Monet. Following cataract surgery in 1923, his colour palette changed significantly; after the operation he painted water lilies with more blue than before. This may be because after lens removal he could see ultraviolet light, which would have given a blue cast to the world. "
Claude Monet - Water Lilies I have seen some of the large water lilly paintings by Claude Monet in the Kunsthaus, Zurich a few years ago in the exhibition, Monet's Garden. These vast canvases are mesmerising - I remember feeling I could dive into the ponds of painted water. From memory, they seemed to be layers and layers of paint to give an infinite depth to the water, not thickly applied but many layers/
Claude Monet, Waterlilies 1907 [My love of art started with Claude (yes, we're on first name terms), since then I've gradually moved away from the impressionists, but this one is still one of my all time favourites.]
