Newton many moons ago discovered that white light is all the colors and can be broken down through a prism, which creates a spectrum. It's been ironic how these little signs from my research draw my attention. Tonight as another glorious sun set over the Tuscan hillside I saw a spectrum on my wall. I just happened to look up and the light was perfectly arranged through a crystal frame on the mantle of my medieval stove/fireplace. A single line of the wonderful colors that create our visual world:). Following that light I saw the source. The sun was setting with an almost identical spectrum. Sometimes I wonder if it's the light that has the color of the atmosphere that captures it.
