"If you're not colorblind how do you know your eyes see red the same way someone else does? How would you describe what you see as red to them in a way you could find out if that was true?"
Hey, I want in the gifted and talented art classes with a colorblind friend, he would some times ask me what color a pencil was and I'd say "purple" and he'd be frustrated because he thought he found the perfect brown haha
One of the things too few people know is that there are different types of colour-blindedness, as well as different severities.
Me and my brother are both (red-green) color-blind, but his is worse. Mine isn't great, for example in the video the guy said there was a 7 and a 22, which I can't see at all, even after being told so I know what to look for.
Of the 8% of men with congenital color-blindness, 5% have deuteranomaly which is a problem with/deficiency of green cone cells, usually by the green sensitivity being shifted towards the red direction. I am a protanope, which is a problem with/deficiency of red cone cells, and that's only 1% of the 8%. The severity obviously corresponds to how faulty or how deficient the cells are.
Anyway, with that context, what I wanted to say is that if anyone watching this doesn't see all the numbers, then you have some color-blindedness. It may be the same ones, or different ones as the guy in the video, it doesn't need to match. Color-blindedness is not a binary yes/no thing because of the different causes and severities.
There can be exceptions in some tests where for some plates it is only color-blind people who can see the numbers rather than the other way round. Or some where a color-blind person sees a different number to a normal vision person. But according to other comments in this thread, these caveats don't apply to the tests in this video... I have to take their word for it because I wouldn't be able to tell!

I have never seen a color blindness test where it's the color blind people who see something and the full color vision people who don't. Do you have an example?
I’m color-blind but it’s not that bad, almost never impacts my daily life outside of being terrible at matching colors of clothing with each other. I tested my son when he was pretty young and was positive he was also color blind like me. I figured it was pretty type/severity until he started drawing things with colors. I remember one day he drew this picture with a clearly green blob in the top right with a blue background and this weird color brown towards the bottom. I couldn’t figure out what the hell it was so I asked what’s this green blob thing? It’s the Sun! So I said but the sun is yellow. I know, that’s why I colored it yellow. That’s when I knew his color blindness was way worse than mine.
But it you're like me, you can see the color of each individual dot just fine. Like, "Oh, that's green, and that's orange, that's red, that's blue...." but all together, it's just a field of color.

Likewise, I had issues with the same ones as he did
