This podcast about color is so awesome.
Wish I could have the eyes of a mantis shrimp! We have only 3 types of cones (photoreceptors) for color vision, they have SIXTEEN! I always feel like there must be colors that I can't see and wonder what they would look like. I will be coloring a picture and looking around for different colors to use and I just can't find them and I realize that's all that I can see.
