Colour Measurement and Mixture

** "Colour Measurement and Mixture" by William de Wiveleslie Abney is a late 1800s scientific work that's all about understanding color by figuring out how to measure it and how we actually see it. The text tells how color is measured and the science behind it. It explores different ways to measure color, emphasizing experiments and scientific ideas about color. At the beginning, Abney talks about why color is important and what he's trying to figure out through his research. He describes doing experiments with the color spectrum, stressing that accurate measurements need controlled conditions. He explains that hue, luminosity, and purity are key to understanding color, but that the subject is complicated because things like light and our eyes can change how we see color, setting up a thorough study of color science. **
