That (quoted) statement is probably wrong (with the uncertainty focused on how the future goes). The Mantis shrimp[1] can see colors in up to 12 dimensions, instead of the pathetic three that we can see. Further, a study done with mice which I can't find now involved implanting mice with the genes for a third type of color receptor, and they grew up being able to distinguish colors in three dimensions instead of two. In other words, if you add a few genes for more color dimensions, the brain adapts. To advance the human capability to perceive color, it is probably just a matter of adding a few genes. This kind of stuff is within a century for sure. Our descendants could grow up being able to see visual subtleties we can't even imagine, if we choose to go that way.
