Regarding the existing human tetrachromats, no, this doesn't obviate the question: I still wonder whether the people who don't have corresponding phenotype are able to have tetrachromatic-like sensations, and whether the choice of the type-four cones makes it any different. Antico has a similar story. A few recent studies have shown that people are better than chance at distinguishing between ill and well faces, possibly based on coloring. The Humans With Supervision | Colorblind Vs Tetrachromacy In the same way that a colour blind person cannot imagine the variety of reds and greens that most people can see, most of us may not be able to picture the rainbow she is describing. Tetrachromacy is a rare type of colour vision that allows people to see colours that other people can't.

In comparison, most people with trichromacy see color in more detail than dogs who are only dichromatic. The crux of Jordans argument lay in the fact that the gene for our red and green cone types lies on the X chromosome. Absorption spectra of the hybrid pigments responsible for anomalous color vision. Tetrachromacy is a powerful tool to a wild bird. Philibert, Victoria The genetics test came back positive, and she began collaborating on a series of experiments with Jameson and her colleagues, including Alissa Winkler at the University of Nevada, Reno.

Most humans can see around 10 million colors.

I always wanted to represent everything I could see. Perhaps this kind of intense experience was crucial to rewire the brain so it could cash in the extra signals her eyes were receiving. In their paper uploaded to the arXiv preprint sever, the group describes the inspiration for their glasses and explain how they work.

It matters because it is possible to have the genes (or genotype) for a trait and for them not to be "expressed" or flipped on. They might see blue and red as the same, even though there is more light information there. What are the evolutionary advantages of tetrachromacy? So far, it looks like Antico's paintings show the same kinds of details that might be predicted by Jameson and Winkler's simulations.
