Fascinating, where can I read the source of this information?

Fascinating, where can I read the source of this information?
Just google it, I am sure there is abundant info on it. My brother as we were growing up and he got his first car, he was delighted with the car and its color, thinking it was a silver gray when in fact it was green. It is often discovered by accident because sometimes if they see red differently than the majority, they still learn to call it red.Flannel Jesus wrote: ↑Sat Mar 25, 2023 6:41 amFascinating, where can I read the source of this information?
Color does not exist in the physical world, it is all energy waves and frequency, colors are how this affects the eye, in other words, color is biological reaction.vegetariantaxidermy wrote: ↑Sat Mar 25, 2023 6:50 am Apparently colour doesn't exist until we have a name for it. Strange but true.
I did look it up, I couldn't see anything saying that. But your example of your brother kinda goes against what you said:popeye1945 wrote: ↑Sat Mar 25, 2023 11:53 amJust google it, I am sure there is abundant info on it.

So in fact your brother's colour blindness was discovered precisely because he didn't learn to call the colour of the car "green" despite it appearing green to everyone else.popeye1945 wrote: ↑Sat Mar 25, 2023 6:33 am Seeing color differently than the majority doesn't mean it's wrong just different. Most color blindness goes undiscovered due to the fact that the color-blind subject learns to call what he sees by the same name the majority call it.

To a person who is partially colorblind, blue looks like what most people call green.
But what if everyone were partially colorblind? What would blue look like? What would color mean to us?
Color is an emergent quality, in the sense that energy wave frequencies are combined with how they affect one's eardrum and how the understanding processes that as color. There would be many variations of how precisely individuals interpret these wave frequencies from one individual to another. With the example of my brother, I agree, perhaps not the best example, but I have no idea how many times that difference would come up mistaking green for silver gray. It is pretty well established however, that what is called color blindness is not that at all, just those who perceive a given frequency differently from the majority standard.Flannel Jesus wrote: ↑Sat Mar 25, 2023 1:38 pmI did look it up, I couldn't see anything saying that.

What you said was at best a partial truth, because in general colour blind people will always have some set of colours they cannot distinguish in the way everyone else does. They cannot learn to call everything by the name everyone else does, only most things.
I don't really think that's a sufficient definition. If it was only a matter of perceiving it differently, it wouldn't necessarily be a "blindness" at all. It's a matter of perceiving it differently, with a few extra properties as well.popeye1945 wrote: ↑Sun Mar 26, 2023 5:55 amIt is pretty well established however, that what is called color blindness is not that at all, just those who perceive a given frequency differently from the majority standard.
It would look like the color of the clear sky, without any clouds at all, in the daytime.commonsense wrote: ↑Wed Nov 23, 2022 11:31 pm

"Color" is a mental state result of our brain's visual area attempting to interpret the energy carried by different light waves. When our sensory system (eyes in this case) is unable to "collect" the information correctly, the stimuli produced is compromised. So in the case that we are partially colorblind...color would still mean the same and our brains will still interpret the stimuli but with less information.commonsense wrote: ↑Wed Nov 23, 2022 11:31 pm If someone is completely colorblind, it must look like the same “color” as everything around it, whatever that may be.

In reality we humans are all partially colorblind...compared to the mantis shrimp(16 color-receptive cones vs only 3 found in the human eye). In addition to that, language and culture plays a huge role in what colors we can see and identify. i.e. in a series of amazing studies, tribes in Africa and Asia fail to distinquish colors that we westerners found obviously different just because they have them under the same name. We also fail to distinquish colors they categorize as different. Specific greens which are important (ir.e. tender leaves for food) are named differently and easily identified by them while we just can't see the difference!Age wrote: ↑Thu Nov 24, 2022 3:24 amHow could ANY one KNOW this or PROVE this, to be true?commonsense wrote: ↑Wed Nov 23, 2022 11:31 pm If someone is completely colorblind, it must look like the same “color” as everything around it, whatever that may be.

For all we KNOW what you call 'red' we call 'blue', and how could we EVER KNOW, for sure?Then EVERY one would just be, so-called, 'partially colorblind', that is what if.Whatever EVERY one agrees with and accepts. Which is EXACTLY like how ALL colours look like, NOW.
How would you KNOW if we are NOT ALREADY ALL 'partially colorblind'?
HOW could this be tested, and verified?
Probably the EXACT SAME as it does NOW, to 'us' who are so-called 'not colorblind'.

Examining the hardware(eye, cons and rods) is a great way to test and verify the differences. Interviewing the individual and asking to make comparisons with different areas of the spectrum is also a good way to understand the differences. Of course there are other more advanced methods.
