Years ago Radiolab did an episode on colors:  
<a href="http:&#x2F;&#x2F;www.radiolab.org&#x2F;story&#x2F;211119-colors&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.radiolab.org&#x2F;story&#x2F;211119-colors&#x2F;</a><p>In the second segment they introduce a potential tetrachromat, Susan Hogan (not the same person as this article). I don&#x27;t remember if her tetrachromacy was confirmed a real science experiment, I don&#x27;t think it was.<p>But I&#x27;d still recommend the whole episode. All three segments were pretty interesting.
