Individuals who have four retinal photopigments are said to have the genes or genetic basis for retinal tetrachromacy (tetra = four, chroma = color). But also like a heist movie, that's when the story gets interesting; it means we have to piece together unorthodox solutions by drawing from disparate areas of vision and color processing.". royalsocietypublishing.org/doi/10.1098/rspb.2004.3009, discovermagazine.com/mind/the-humans-with-super-human-vision, web.archive.org/web/20120214002707/http://www.klab.caltech.edu/cns186/papers/Jameson01.pdf, jov.arvojournals.org/article.aspx?articleid=2191517, neitzvision.com/img/research/CV-ReasonForEyes.pdf, bbc.com/future/article/20140905-the-women-with-super-human-vision, journals.physiology.org/doi/full/10.1152/nips.01376.2001, Deuteranopia: How to Tell If You Have Red-Green Color Blindness.
