There's an article debunking it at snopes.com:http://www.snopes.com/politics/medical/tetrachromacy.aspOne of the problems with it is that computer monitors don't provide enough color resolution for such tests to work.And as if that weren't bad enough:"Additionally, the claim that 25% of people are tetrachromats is inaccurate. While Jay Neitz, a color vision researcher at the Medical College of Wisconsin, estimated that half of the female population has a fourth cone in their eyes, only a small number of those people can actually see additional colors."Neitz told the Pittsburgh Post Gazette in 2006 that only about 2% of the female population are tetrachromats. Newcastle University neuroscientist Gabriele Jordan said that the number may be higher (about 12%), but in 20 years of research she has only been able to confirm the condition in one person..." The article also says that tetrachromacy is sex-linked: it requires two X chromosomes, so you XY ladies are out of luck, I'm afraid.
Quote from: Sam314 on March 02, 2015, 05:21:36 PMSo now that I'm back from Sking and my brother's Ariana Grande concert, I checked the replies at my last asked question on "What Color is the Dress" (https://www.susans.org/forums/index.php/topic,183822.0.html). Found it very much fun to see how others see it. But what I also found was an email from my former art teacher who found a very cool article that finally answers the question as to why we are seeing it so differently. There's a neat little color test here to show you how you see colors for yourself and all the sciency cones stuff. Try it out. Learn your title:https://www.linkedin.com/pulse/25-people-have-4th-cone-see-colors-p-prof-diana-dervalI learned that the reason I see it the way I do is cuz I'm in the 25% of people given a 4th cone in my eye to be able to see the dress as it truly is. I am a tetrachromat with seeing 36/39 of the colors. Find it odd though not seeing the last 3 colors. I know where they are due to thickness but can't see the separation of them. Very odd feeling. And also realized I don't own any yellow. Guess this is why :p
