I hate to be 'that guy' who asks silly questions among a group of highly intellectual individuals, but I didn't know where else to go for a scientific answer. I'll provide the main question up front so you don't need to go digging for it: do colors exist outside the field of human vision? I've been having a conversation with my friend (an art major) about this, and I'm having a difficult time discovering the answer. I understand that the human eye has three cones (color) and three rods (amount of light) There are many animals out there that have more resources at their disposal. Most notably, the Mantis Shrimp, which has 12 cones capable of receiving color. I understand there is a difference between light and color - but I also [vaguely] remember that color also can be mapped out via a spectrum of wavelengths. I'm stumped, any insight?
