That nonsense post about tetrachromatism is going around again. Here’s a link to a “why that post is nonsense” essay someone posted two years ago as my tiny, futile effort to stop it!

I am a fan of dispelling misinformation and spreading actual science, so I’m passing this along even though the language is a bit stronger than I typically use myself.

Enjoy.

OH THANK GOD I spent all morning debating whether I should be correcting the damn post myself
for the love of fuck your computer screen only produces RGB light

I’m not sure the RGB thing is a relevant point. But something that is worth noting is that the color gamut of most computer screens is crap regardless of which colors they’re producing.

YOU ARE NOT A TETRACHROMAT, AND THIS GRAPHIC IS BULLSHIT
