tilthat: TIL a philosophy riddle from 1688 was recently solved. If a man born blind can feel the differences between shapes such as spheres and cubes, could he, if given the ability, distinguish those objects by sight alone? In 2003 five people had their sight restored though surgery, and, no they could not.
nentuaby: I love when apparently Deep questions turn out to have clear empirical answers.
way more basic: Is the brown I am seeing the same brown you are seeing? Nobody knows.
I had a conversation about this decades ago and it stuck with me. It’s bothered me all this time. I have to believe our color perception is at least close if, biologically, we have rods and cones that operate in the same way, and brain structures that work the same. (To keep it simple I’m not considering colorblindness).
What I find really fascinating is some higher level things that I didn’t realize were different between people.
Some people see things in their mind’s eye and those with aphantasia struggle to do so if at all.
Some can envision and manipulate things in 3d and some have a harder time with this.
Some people like me with ADHD have what is called time blindness, “difficulties with tasks related to time, such as estimating how long an activity will take, sticking to schedules, and recognizing when it’s appropriate to start or finish tasks.” (Healthline.com). My perception of time is … limited but it is hard to describe exactly what I’m missing because I don’t know what it is like to be normal.
I’m sure there are other examples as well.
Some people have an inner monologue, like they hear a voice narrating their thoughts. I dont have that. I have aphantasia too but apparently there is no relation no matter how weird I think both groups are.
Ah right. That was the one I was forgetting. I’m often talking in my head to think unless I’m thinking visually.
If I may, how does your thinking work?
I’m not so much narrating my thoughts as using words to think things. E.g. in my head I say, “how do they do that? I have to have words to express the thoughts”
Or another example: when I am typing I am basically “dictating”, but by speaking inside my head and typing what I “say”.
Are you able to just …conjure concepts and ideas without words, somehow?
There really is no good parable to describe my thought process. It’s abstract. I’m often quicker to conclusions than my peers so there’s that. If I had to look at pictures and read an audio book along the way it would be slower.
I can think about a painting, but it doesn’t appear in my head other than I’m thinking about the facts about it. I know that The Scream by Munch is a ghostly figure holding his head screaming and walking on a… bridge? That is just remembered stuff about it that I pulled from my thoughts and memories. I don’t know the color theme, direction he’s walking or other details. I can probably spot the real one in a comparison with a similar painting so it’s stored somehow, I just can’t access it as is. I can’t draw for shit.
I can think about a page of a paper that I’m going to write. I can form the concepts, rules, theme, paragraphs and flow of it and have it all done in my head before I start writing. Then I type it down at 100 wpm until the page is full. At no point did I hear anyone narrating or think about what any of the words would look like when printed out. It was all abstract until I started thinking about how to put it on paper.
So fascinating.
I really wished I could write like that. Probably because of poor working memory (thanks ADHD) I can’t hold that much stuff in my head prior to writing. Certainly not a bunch of raw wordless concept blobs (or whatever?) plus flow an form and all that. Jeez. I invariably write things as I go. I might have a vague sense of what I want to write. Certainly nothing “done” before writing.
I can “see” a rough approximation of The Scream in my head. Enough to draw an inaccurate copy. I can draw other stuff (cars, bicycles, cats whatever) by visualizing them to greater or lesser degrees.
My kid has aphantasia and described it like you did. Remembering facts about it but not so much the actual image itself. Interestingly she is quite good at drawing.
I’ve heard that it’s much easier to learn how to draw when you can make an image in your head and trace it down on paper. It’s still possible to become good at drawing with aphantasia but in my case, I can’t make up new imagery from my thoughts so I have never had that as a reason to draw, if that makes sense. I just don’t know what to draw, so I don’t.
Art does nothing for me anyways, so I don’t feel like I’m missing out. I have never looked at a painting, sculpture, dance, theater or other physical forms of expression and felt anything about it. I can only objectively observe it, like ”this painting of a boat is blueish and painted with oil on canvas” or ”this person moves their legs and arms in this fashion while singing about loneliness”. This might be more due to autism than aphantasia though. Still it probably contributes to why I can’t draw.
Based on my life experience being like mild-moderate red-green color blind, I think everyone else sees the same colors except me :(
They say this but we have the color wheel. It is trivial to find clothing that goes together, or colors that can invoke a mood. If we really did have alternative experiences I cant imagine it wouldn’t have been qualified, understood, and addressed by marketing already.
Orange and blue means action

Those are cultural associations though, not biological
Are they? I am sure you must have seen art forms from centuries ago from cultures very alien to your own and were still moved. But even if it was cultural you would still have to wonder why no one is catering to that culture. If a segment of the population really did see colors differently wouldn’t someone make stuff for them to get that market?
Just look at how associations between color and genders differ between cultures and change over time. Those differences absolutely exists, you’re just not seeing it because you’re not the target audience
You mean one time?
If most of history is just one time

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8451877/
Very well. Please tell me about the past twenty or so times that boy girl color associations changed.
Even it happening one time is enough to disprove it not happening.
Irrelevant

Looking at it with the concept of mathematical equivalence in mind, the behavior can be almost the same yet internal representation can still be wildly different
You are just making a statement that has no connection to what I wrote. Human beings have preferred color combinations. Address this first.
1+1 = 2
2/2+2/2 = 2
Sqrt(2+2) = 2
The internal experience can be very different despite having outwards similar expressions like shared preferences.
Why the differences would cancel out wouldn’t necessarily be easy to explain, and sure it implies big differences are rare, but it’s not impossible. Especially because we already know of many existing biological differences which still produce similar outcomes (in part due to redundancies) like in chemical balances and protein expressions, very commonly seen in differences in the gastric system
Do you have evidence from neurology that this is happening?
For starters
https://www.scientificamerican.com/article/scientists-surprised-to-find-no-two-neurons-are-genetically-alike/
I am skeptical that colors universally bring about moods or concepts. One would have to prove this is true despite cultural conditioning that ascribes meaning to different colors.
I also doubt that each person experiences colors in a significantly unique way. Unless we can show that the receptors in our retinas, or the neurons receiving those signals, behave differently from person to person. I have to wonder if widely appealing art (that uses color) could even exist if we didn’t share the underlying mechanisms of seeing and reacting to its colors.
Very well. How do we account for the associations we all have? Who sat you down and told you that distant colors should invoke excitement? That vibrant colors were fun to look at? That judges almost universally in cultures separated in time and geography should wear black or that red would be popular with people one rank below the boss? Or that cool light means focus and warm light means relax?
I just find this whole idea that it is just cultural to be indirect contradictuon to what I have seen. Especially when I am thinking about all those traditional artforms. People a thousand years before I was born making stainglass, or murals, or painted pagodas that are still amazing to look at despite the vast differences in cultures between me and the artist.
I also don’t recall the conversation when I was a kid in trailer park in the Appalachian Mountains when my parents say me down and said “remember to feel a sense of awe and dread if you ever see a 1200 year old Buddha statue wearing a white/gray robe popular among Indian Royality from that time”. Pretty sure I would remember that conversation and it also wouldn’t have been a gut reaction.
I didn’t say I was opposed to the idea or that I was discounting it out of hand. I simply said I was skeptical (unwilling to believe something just because someone says so) and mentioned a way to think through it scientifically. Then You kind of bombarded me with a lot of claims and anecdotes… Eek. Hold your fire lol
Those are all compelling things you list and it piques my curiosity further. But these things aren’t rock solid evidence. Sure it’s possible. But not very convincing. We can do better. So yeah, I’m curious to tease out what color associations are learned versus hardwired.
“What you have seen” never makes for unassailable evidence on its own. That’s because you, like every other one of us humans, is affected by myriad cognitive biases that can skew your conclusions. (Which is how we got superstitions and old wives tales)
Also, it almost sounds like your argument is that the only way for these associations to occur is through being taught directly and explicitly. But there are other ways to learn things. Kids pick up on all kinds of unspoken things. When going, they often look to their parents for their reaction to some things. They learn a considerable amount of language without being explicitly taught. Musical associations happen without explicit teaching and that definitely varies by culture.
One can just seek evidence to support their conclusion and ignore all the other possible causes or counter examples or whatever else.
For example, cool light (by this you mean light on the blue end) means focus and warm light (on the red end) means relax. Hardwiring is one explanation. But simple learned associations could be another.
Assuming it is true, perhaps orange / yellow / red tints make us relaxed because of associations with sunsets and candlelight. Or something along those lines. Would humana who grew up with a star producing a different light spectrum have a different interpretation? Can people be trained with different associations?
The premise itself has to be tested as well. Is it truly Universal across many cultures? How many cultures have you proven this to hold for? And how did you prove it? By asking? Or by sound experiments? Were those experiments duplicated by others?
Oh also you are unlikely to remember much of anything prior to the age of 3 (give or take). So maybe your parents did have those conversations but at a very young age.
Maybe studies have been done about a lot of these things. I would be curious to see them. But now I’m tired and need to turn my brain off.

Fair, as long as it is fast action. You wouldn’t want to have to make 3 movies of people walking.
I’ve thought about this my entire life. Just generally, is what and how I see the same as you? It’s obviously a matter of how an individual’s brain interprets something, so we won’t know until we can plant our consciousness in someone else a la Black Mirror.
Even that won’t work. Pretend we’ve figured out how to that. How do we calibrate it? What if I transfer my memories into your mind, but you see the sun as “blue”, and so on in my memories? What if you recall a memory where I’m laughing and smiling, but the emotion I’m recalling is what you would call “sadness”?
Either our subjective understanding of reality differs, or the machine doesn’t work right. The machine faces the same issue as our language does when it comes to reliability of translating internal states.
I guess the same could be said about any of the senses. Taste, Sound, Touch, smell.
What does that even really mean though?
Does red look red to you? It looks red to me. What does a difference in perception really mean at the end of the day?
I think yes. Light is a wavelength, so whatever colours we are seeing are in ratio to one another. There might be some perpetual variation due to the quality of our eyes - but red orange and yellow are next to each other on the spectrum.
Nobody will see that any differently.
Unless your eyes are the ones converting the wavelengths, then it still is not sure to be the same with everyone.
We could flip the colour spectrum and all the colours that should be next to one another still are.
