Color Podcast

      In the start of the podcast, I found it interesting that they mentioned light, or light from the sun, was seen as "holy."  People during Newton's time thought the rainbow produced from the prism was "dirtying" the light.  It was interesting that Newton himself was responsible for determining that light, and the colors within that light, were a physical object that could be understood.
      I did not know humans had 3 "cones" which enabled us to see certain colors, and it is weird to think butterflies and mantis shrimp can see more colors than humans can.  Regarding the women with extra cones, I knew people could be color blind, but I never thought of humans with the ability to have more cones and to see more color.  It was fascinating that in a clear blue sky, the woman with the extra cone was able to also see some red.
       I think it was fascinating that Gladstone admired Homer's works so intensely that he was able to dissect his writing to determine that Homer was actually color blind.  Additionally, in different cultures of the past blue was not mentioned as nearly as often as other colors.  For example, they mentioned that Homer did not use blue at all in his writing.  I did not know that without prior knowledge of the color blue, it is so hard for others to conceptualize.
