Color vision: Theories, afterimages and more 

Great lecture! I'm studying color theory as a fiber artist, and this is a fantastic description of both the trichromatic and opponent process - I'm sharing with my fellow quilters.

Genius... best exposition on color theory !

This was really helpful. Thanks

So helpful! Thank you

On Wednesday, March 2015, Avalanche Biotechnologies in Menlo Park and the University of Washington in Seattle announced a licensing agreement to develop the first treatment for colorblindness. The deal brings together a gene therapy technique developed by Avalanche with the expertise of vision researchers at the University of Washington. "Our goal is to be treating colorblindness in clinical trials in patients in the next one to two years," says Thomas Chalberg, the founder and CEO of Avalanche. The agreement has its roots in a scientific breakthrough that occurred six years ago. That's when two vision researchers at the University of Washington used gene therapy to cure a common form of colorblindness in squirrel monkeys. "This opened the possibility of ultimately getting this to cure colorblindness in humans," says Jay Neitz, who runs the Color Vision Lab at UW along with his wife, Maureen Neitz.

wish he woulda explained positive after images too, ive had them for a couple years

Can you explain why Protans and Deutans see the same color results (blue/yellow) as oppose to Tritans that see Red/Cyan. I just don't understand why they see similarly.

While color is a mental construct, so is sound.

How long will I wait for human trials for gene therapy for red green color blindness?

Gene therapy for red green color blindness please. In my opinion, its visual impairment. I cant discriminate some colors. I cant get my dream professions. My sight of color is very limited. Please help me and 350 million people whom color blind🙏😭

Your are incorrect. The answer is A and B. I can prove this with a simple experiment. Reply if you are interested. ..

This sounds really racial
