Will There Ever Be New Colors That We Can See?
If we allow for future evolution, then it is possible that humans might develop different types of color sensors in their visual systems and new types of processing to allow them to experience new color perceptions. Therefore, while new techniques for producing stimuli that evoke color sensations will certainly be developed (e.g. today’s televisions easily produce stimuli that the televisions of my childhood could not muster), color is ultimately a perception and limited to the capabilities of the human visual system. “If we allow for future evolution, then it is possible that humans might develop different types of color sensors in their visual systems and new types of processing to allow them to experience new color perceptions.”
