How to Actually Test for Tetrachromacy (Stereo)

📌Yes, there's no number in the Ishihara plate of the thumbnail. But if this was a real test for tetrachromacy and you are a normal trichromat, you wouldn't be able to distinguish the red/green number from the true yellow background. This video shows you how to actually test for tetrachromacy because practically most tests, even those designed by renowned tetrachromacy researchers, are fundamentally flawed because they don't respect the two-dimensionality of tetrachromatic hues. Alternatively you can also watch it in VR; on your mobile phone with the cardboard VR mode enabled and by crossing your eyes; or via temporal colors by rotating the VR video's screen by 180° horizontally; in order to see these the impossible color combinations!

And I will show you how to reshape and enhance your sensory experiences, because it is nothing but our senses that connect us to this world. Thanks for watching! 📌My name Ooqui is pronounced like this: "Oo" like the "Oo" from "Oogway" and "qui" like "quiet" without the "-et" at the end. ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ 📌 My official Twitter account: https://twitter.com/OoquiOoqui (currently inactive) 📌 "Ooqui Sensory Lab" Discord: https://discord.gg/Bc7qesQW85 📌 Website "Color in Color": https://www.color-in-color.info ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ 📌 Music: Mostly custom made music for this video.

Unity Recorder is used for recording the animations as a video. FL Studio was used to create the background music. I used my mobile phone to create real-life videos. PhotoScape X (Pro) & FireAlpaca (and seldomly also ChatGPT) were used to create some of the art. As for the voice you hear, it's a clone of my own voice, generated with ElevenLabs voice cloning feature.

I did not "cheat" by closing one eye or the other during the test. I can actually see the true-red tetrachromatic colors as subjectively new (tetrachromatic) colors, which is why I can finish this test so fast. ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ ◽ 📌 Sources & Useful Links: (Last access of all links: 20.04.2025) - More info on "true-red tetrachromacy" on my website (work in progress): Lachner, K.
