I see things as more blue than they are according to my family lots of things that I see as blue they insist are actually green.
I really liked this article, you made it easy and interesting, good job. Chances of zero cells in either eye expressing the mutant chromosome instead of the normal one are really not that good.
Whether this is of any practical value is another matter. I always assumed the slight diffrence in white balance in each eye was normal and something everyone had.
It probably balances out to a normal color representation as long as you have two functioning healthy eyes anyway since the white balances seem to cancel each other out..
I also have very slight short-sightedness, wich is worse in one eye, so for a while I did loads of quick switches between the two to determine if one of my eyes was really worse than the other, before going to an optician.
I just took the online color test, and i got the score: 0 which is a good thing , I have also completed all of the puzzles in blenduko 2 with a time below the world average on all of them and i have a score on in their color IQ test.
Is there any way I can find out? Not on a computer screen, no matter what the venue. Almost no one is, to the point that it took thirty years of study to even confirm that such a thing was possible.
They gave me a colour test like this when I was younger because my eye doctor suggested it to see if I was colour blind. When I was younger my mother would mix paint for her hobbyist paintings.
I apparently asked on multiple occasions what she called the colours. That it was something else. Can you imagine me rolling my eyes at this point?
I got put in time out more than once for having this argument with my mum. Eventually, it snowballed into this fear that I was colour blind.
I had also freaked her out by coming out with white hair and pasty white skin. She assumed I was albino. My mother is a freak.
I was just pasty all my childhood because the outdoors sucked. I wanted to read more than play outside. It happens.
I digress. Well, the eye doctor did a colour test on me. I got to sit in a box and had colours flashed on a wall and I had to identify them.
So he showed me again and asked me to describe it. He was testing for red deficiency I think or something.
But It was a mix of green and red or whatnot. All in all, he suggested to my mother that I might be something like Tetrachromatic. Because I was picking up subtle changes in hues of light that apparently should not have been possible for seven or eight year old me.
My crazy as a bat mother told all her friends her daughter could see more colours than the average person. And I died of embarrassment every time.
To even think about diagnosing DIchomatic, you need to go to optometrist. For any eye related test, you should see a licensed professional. Not your computer monitor with a gradient scale my 5 year old nieces could put together.
Purple is the hue of grapeskins, between pink and red. Violet is between blue and lilac. Lavender is pretty much violet and indigo pretty much blue.
Sometimes I distinguish blea and turquoise, which I call shore, where blea is between shore and blue. I would think that it would be easy to figure out now days.
Does the television or computer screen look different or bland compared to real life? For me, the TV and computer screen look perfectly accurate as compared to what I see on a sunny day.
My son was color blind and it took an eye dr to figure that out. He favored pink shirts and everyone thought that he was courageous and making a bold statement.
Turned out that he had no idea that he was wearing pink. He got a lot of compliments, so he went with it. I know the feeling. Had a purple shirt that I loved, and I thought it was blue until my mom pointed it out.
Funny you should say that… TV screens and especially Movies recorded on old film look really wrong. The colours are different especially flesh tones.
In any case I have arguments with my family over blue and green all the time. I see things as more blue than they are according to my family lots of things that I see as blue they insist are actually green.
Rather than tetrachromat I think this means that I probably just have extra blue cones or that my brain weights colours more towards blue which is also my favourite colour.
Sunlight burns my eyes and I have to wear sunglasses most days even on overcast days or it feels like my eyes are being stabbed.
Presumably one way to infer if you are a tetrachromat would be if there are colors you see in real life that never appear correct on a computer screen.
I actually, honestly am a Tetrachromat, I do see more colors than normal. I respect you trying to do all this research but this article is not really true.
Functional tetrachromacy is exceptionally rare. And in thirty years of research, one single person has been found to have functional tetrachromacy.
Maybe you also have it. Maybe you should use your special eyes to take a good hard look at yourself and how you make arguments.
I look forward to hearing from you. Your article is excellent. Despite that some of us will have to forego feeling special, if we want to be critical of what is set up to be the truth.
The optometrist that diagnosed my son used to do work for the military. I really like this article, because is scientifically grounded yet very readable and simple to understand.
I have come across the term of tetrachromacy yesterday and it really amazes me … I believe in the science here, that it is very rare, at least in the population which has been tested for.
I can really see how these women with the functional four cone cell were seen as crazy and delusional through the history … however rare they were.
And I am just wondering how many different mutations there are in different bodies, and how astonishing fact it is, that our body, our senses, are truly our window to reality … So please, always believe in magic, because what is magic for someone, it just might be the reality for somebody else!
I have recently seen an exquisite degree google image of an ancient Temple of Hathor in Egypt. Eons of soot were cleaned off the ceiling to reveal blue paint..
Interestingly, when I first saw this image there was something magical in that color…it was golden. So how do you explain that I see 39 colors as well as my father does, but both my sister and mother see less colors even less than 20?
Does it mean they are color blind? I do undesrtand all your arguments and agree with them but I have the doubt about on why some people see less or more colors than the others.
Mainly because like you said, my monitor can only have 3 shades of colors at various degrees creating the illusion of color. Our brains made up pink to connect red and purple.
Pretty much it was our brains way of completing our color definition range. Light is light until the brain makes it something else, our brain knows when different wavelengths of light are entering the eyes when the cons in the eyes fire up and tell the brain….
So yes even if you had more cones it would not change much sense the brain still uses the same colors to code each wavelength. Your title is misleading, you admitted there are tetrachromats.
There are more ways in which this is possible, than sone pll think. Long before computers were in homes and most businesses back in the early 80s, I worked in a photo processing lab.
I was told then that I was one of the few people in the country who scored that low, which is the best score you can get.
I am a true tetrachromat! The test was just like the computer test… the color chips had to be arranged by shades and tints just like the computer test.
Only two women empirically proven to be tetrachromats. How do they view the night sky, a rainbow, a forest temperate or tropical?
Colors are a luxury! Interesting article! It does seem that some people are more sensitive than others when it comes to seeing colours though.
Is it possible that this might be to do with how many rods and cones you have? Typically aphakia occurs due to surgical removal of the lens due to cataracts.
If new lenses are inserted, the person is then pseudophakic, not aphakic. Very rarely humans can be born aphakic without a lens. One minimal thing: Many mirrorless camera sensors i.
This can be easily tested too, such as by pointing a phone at a remote. Never heard about this. You say people from northern Europe are more likely to have it; Do you have a source for this claim?
Only because i want ro read more about it. I am a Norwegian woman and my father is red-green colour blind. If I would want to do a scientific appeoved test, is it possible?
If so where should I go and who should I see? It would have to be carefully calibrated ink or paint swatches. I wonder if the rareness of functioning tetrachromacy, given how common the trait should be, genetically, might be due to habituation laziness.
See if it can be trained. I have a lot of northern european heritage, my 23andme results report. My other daughter is very sensitive to the differences between colors and may think colors clash, two different shades of red for example, when others seem oblivious.
If they were, maybe it would revolutionize indoor lighting. Personally, I think my eyesight is most likely just an adaptation to ancestral lands that had long, dark winters.
That seems to make sense anyway. Interestingly enough, both my daughters like the arts but the colorblind one works almost exclusively in graphite pencil while the other is now exploring painting too.
Why do some go that gaga over tetrachomacy being a special gift when we can all advance our skills and senses so much just by exercising them, with some instruction hopefully.
Sadly, shop and art classes have been cut from school budgets for decades in many places. Formal art education has been hobbled in other ways for about a century.
The language arts have suffered too, in the US. So yeah, the science of vision rocks but both vision and perception are affected by how we exercise and train them.
If you took that same child and instead of blindfolding them, you immersed them in the arts, they could more fully enjoy being a tetrachromat.
The same would true for people with different sorts of vision or other traits — let each develop and bloom with what they have because that powerfully and functionally changes what we have and who we are.
My wife is terachromat, and aphakia thanks to a slight genetic anomaly. Hair has three pigments, one black more widebandly darker than the others.
Can the white skin tan or not? Not that this speculation matters any; the two lower cone pigments should correspond to violet and dusk, not seen in skin or hair.
Nothing is more annoying than arguing that there is a thousand or more different colors of each basic color with someone who can not see what I see.
For the first thirty years I never thought much about it, and assumed people saw similar to how I do. The funny thing is, apart from people missing one type of cone, there is no such thing as color-blindness.
As explained, we only have three sensors for the whole spectrum of visible light. Because of this simplification, there are many different spectra that will look the same even to non color-blind people, although they are different check metamerism.
But we call them color-blind simply because we focus on how their difference is a problem in daily life. So people who claim to be tetrachromats might just be what we usually call color-blind.
I have been in a full blown argument with my friends over the color of my shirt. My friends keep telling me it is strictly green..
It was making me feel fricken INSANE until I realized that being assigned female at birth, there was a chance I saw more color than some of my friends do.
Pure-frequencies are also shoe-horned into a mixture of three response levels from the three color sensors. There is enough overlap in the bell-shaped response curve of the green and red sensors that a pure red laser, for example, is going to tickle the green receptor a little, and even the blue receptor may respond ever-so-slightly.
Photopigments in these three types of cones give you your ability to perceive the full spectrum of color. This molecule is known as cis retinal.
This results in your ability to perceive those colors. The spectrum is better known as ROY G. The existence of this extra photopigment may allow a tetrachromat to see more detail or variety within the visible spectrum.
This is called the theory of tetrachromacy. While trichromats can see about 1 million colors , tetrachromats may be able to see an incredible million colors, according to Jay Neitz , PhD, an ophthalmology professor at the University of Washington, who has studied color vision extensively.
The typical human being has three different types of cones that divide up visual color information into red, green, and blue signals.
These signals can then be combined in the brain into a total visual message. Tetrachromats have one extra type of cone that allows them to see a fourth dimensionality of colors.
It results from a genetic mutation. The tetrachromacy mutation is only passed through the X chromosome. Men only get one X chromosome. Their mutations usually result in anomalous trichromacy or color blindness.
A mother or daughter of someone with anomalous trichromacy is most likely to be a tetrachromat. One of her X chromosomes may carry normal M and L genes.
The other likely carries regular L genes as well as mutated L gene passed through a father or son with anomalous trichromacy.
One of these two X chromosomes is ultimately activated for the development of cone cells in the retina. This causes the retina to develop four types of cones cells because of the variety of different X genes passed on from both mother and father.
In some species, tetrachromacy is all about survival. Several bird species, such as the zebra finch , need tetrachromacy to find food or choose a mate.
And the mutual pollination relationship between certain insects and flowers have caused plants to develop more complex colors.
This, in turn, has caused insects to evolve to see these colors. That way, they know exactly which plants to choose for pollination.
You may just take your ability to see extra colors for granted because you have no other visual system to compare yours to. The first way to find out your status is by undergoing genetic testing.
A full profile of your personal genome can find the mutations on your genes that may have resulted in your fourth cones. A genetic test of your parents can also find the mutated genes that were passed on to you.
The color matching test is the most significant test for tetrachromacy. It goes like this in the context of a research study:. True tetrachromats will rate these colors the same way every time, meaning that they can actually differentiate between the colors presented in the two pairs.
A subject in the Journal of Vision study , known only as cDa29, had perfect tetrachromatic vision. She made no errors in her color matching tests, and her responses were incredibly quick.
Her story was later picked up by numerous science media outlets, such as Discover magazine. While your own chances of being a tetrachromat might be slim, these stories show how much this rarity continues to fascinate those of us who possess standard three-cone vision.
