What if what my brain interprets as green yours interprets as hot purple?
I get that it’s a joke, but bottom line? The names of colors are just the way our brains interpret specific wavelengths, and wavelength is objective. So it doesn’t really matter, because the wavelength of the photon is the same regardless of how our brain perceives it
But that’s correlation, the way the brain conceptualizes it into a “color” in the mental model, well that’s the qualia stuff referenced in another comment.
Wavelength may be objective, but the signal that a brain receives may be different if the cells which are supposed to receive that objective wavelength aren’t functioning correctly.
Like if I make you wear rose coloured glasses, it doesn’t matter what colours I show you, you won’t be able to name them correctly because the objective stimulus is literally coloured before it makes it to your brain.
Except the rose-colored glasses example doesn’t really disagree, because the colored glass is absorbing all the photons except the pink ones, so you’re really just further making my point.
Have been working with two red-green blind people for some years. They told me they didn’t know for the longest time. One of them became an electrician, the other one was disqualified since he couldn’t differentiate between red and green. That’s how he found out. The electrician guy found out years later once he questioned why his colleagues get the different coloured wires right all the time but he didn’t. Both of them see red and green in different grey shades, they told me something like blacker greys are red and whiter greys are green.
Ha! I had an electrical engineer friend with a similar story. He thought manufacturers were idiots for colour coding their cables with shades that are so close to each other.
I think he’d been in the industry for about 5 years when he found out…
That’s hilarious I love it. My prior coworkers were so confused by pink & lime green and those sorts of similar shades.
I had wired Ethernet in my whole house. Feeling like a complete dunce at having to give 3 tries for each termination. Before realizing two years later that i was red-green colorblind.
After that diagnosis i felt so fucking validated.
You got my meme bro.
I mean they literally do. How do I know your colors are the same as mine?
Talking about colour blindness is a bit misleading as tried colour blindness is very rare but having a red-green colour deficiency is quite normal, men having some 14.5% prevalence. (Women only like less than a percent)
I have diagnosable deficiency, but it really doesn’t come up in real life unless there’s like a really deep metallic colored car which might be harder to correctly identify or cause a bit of debate.
Like you wouldn’t call someone blind because they can’t read subtitles from a somewhat faraway TV without glasses. You’d just say they don’t have the greatest vision.
I know someone that didn’t realize they were red/green colorblind until they were a teenager.

This video is great at showing non-colorblind people what some colorblind see. The woman’s son is colorblind, so she does a little interview with him, to ask him how he picks out certain colors. They also take some pictures and run them through a filter that demonstrates how he sees - to a non-colorblind person, the difference is obvious, but he struggles to tell the difference, indicating the filter does a good job of showing what he sees.
My partner is colourblind and his job as a “paint expert” involves mixing paint every single day. He can tell the difference between his shades of gray just fine usually.
Scientists need to observe him.
some do, and some don’t! this is definitely a thing that happens, finding out your color blind as an adult. most often when people try to so things like get pilots licenses etc
yes, they do find out when they are young. in many countries they get tested even. most just can’t see the difference of two colors, eg red and green. usually traffic lights are in a certain order, so it works for them.
we will never know if red looks green to them or green looks red to them. they still can see it’s not grey.
This is an interesting book about growing up with color blindness https://a.co/d/hVKjvDd.
