Is your red a different color than someone else’s red? A study of color blind cells reveals.

【My red and your red are different colors?” A surprising discovery from a study of color vision cells on a question we all ponder at one time or another.】


・The subjective sensory experiences of each individual are called “qualia,” but it has been difficult to prove whether one’s own qualia are the same as those of others

・However, research conducted at Johns Hopkins University (JHU) in the United States has confirmed how the color vision cells in our retina are produced and in what proportions, and has produced results that may answer this longstanding philosophical question.

The researchers state that “even among people with normal color vision, colors may appear slightly different for the same apple.

・Humans possess some of the highest levels of vision in the animal kingdom. Humans outperform most mammals in color vision, being able to distinguish millions of colors. (In the case of dogs, there are only two types of color vision cells, blue and yellow, and they cannot accurately perceive red and green.)

Between the individuals with the lowest ratio and those with the highest ratio, the ratio of L-cones differed by a factor of more than five. If the ratio of red-detecting L-cones is this large, the red signal delivered to the brain may differ greatly among individuals, and the perception of redness may differ even when looking at the same red apple.

・It indicates that families drawing the same genes are relatively more likely to be the “same red” if they are from the same family.


The above is a quote from the article






We all live in a world of different senses.


Is the “red” that I see and the “red” that others see the same (similar) color? Is it possible that what you perceive as “blue” may be called “red” by others?


Have you ever imagined something like this?


I used to imagine that.^^


This experiment suggests that people may see redness differently when looking at the same red apple.


It is not so much that “red for me is blue for them.”

Redness seems to be seen differently by different people.

(If family members drawing the same genes see the same, does that mean that people with different genetic information see colors differently?)


Although the results of this experiment are a little peculiar, measuring retinal propagation of eyes donated after death, it is highly likely that each individual sees colors differently.


To begin with, consider,

Different people smell differently, and different smells are pleasant or unpleasant,

People perceive heat, heat, pain, etc. in different ways.

Each person’s senses of hearing, smell, taste, and touch are also different,

So it is not surprising that each person’s sense of sight (color) is also different.


When you think about it that way,

It may be safe to say that each person lives in a different sensory world or universe.


It may seem a little sad to say that everyone lives in a world of different senses, but I think it also depends on how you think.


If you assume that you and others are the same, there will be conflicts when you discover that you are different,

But if you assume that you and others are different, I think it is less likely to cause strange conflicts.


I feel that people who are constantly blaming, denying, or getting angry tend to assume too strongly that “we should be the same.

If we assume that we are different, we can enjoy our differences, make efforts to find ways to make up for those differences, and feel happy when we find similarities.


Of course,

Of course, it is important to assume that people and oneself are the same,

But if we could also have the premise that “people and myself are different,” we could build a kinder world, both on an individual level and on a larger one,

I believe that we can build a kinder world, both on an individual level and on a larger scale.


These are just a few of the many thoughts I had about “different” in an exaggerated way, based on an experiment suggesting that one’s “red” and another’s “red” may be different.



See you then



The more different a person’s genetic information is, the more likely they are to appear different. So, if you say, “This person feels completely different from me,” it may be possible that he or she has considerably different genetic information from you. Such an interesting idea may be possible.
