Now in this thought experiment, you as a listener are trying to guess which physical color I meant. I say yes, because my chip is in fact one of those. Then you split your set in half and guess again. The number of guesses it takes the ideal listener to zero in on my color chip based on the color word I used is a simple score for the chip.
Using these scores, we can now rank the colors across the grid, in any language. In English, it turns out that people can convey the warm colors — reds, oranges and yellows — more efficiently with fewer guesses than the cool colors — blues and greens. The left-to-right ordering is from easiest to communicate fewest guesses needed to get the right color to hardest to communicate.
The diagram shows that all languages have roughly the same order, with the warm colors on the left easy to communicate and the cool ones on the right harder to communicate. This generalization occurs in spite of the fact that languages near the bottom of the figure have few terms that people use consistently, while languages near the top like English and Spanish have many terms that most people use consistently.
In addition to discovering this remarkable universal across languages, we also wanted to find out what causes it. Recall that our idea is that maybe we introduce words into a language when there is something that we want to talk about. So perhaps this effect arises because objects — the things we want to talk about — tend to be warm-colored. We evaluated this hypothesis in a database of 20, photographs of objects that people at Microsoft had decided contained objects, as distinct from backgrounds.
This data set is available to train and test computer vision systems that are trying to learn to identify objects. Our colleagues then determined the specific boundaries of the object in each image and where the background was. We mapped the colors in the images onto our set of 80 colors across the color space. It turned out that indeed objects are more likely to be warm-colored, while backgrounds are cool-colored. You see them in different shades because your mind does not fully listen to the eyes, but it makes all kinds of adjustments.
All colors are formed in your mind! That means shades of that color. A normal man has three kinds of cones, the total number of colors he can see including shades is:.
Before exploding with delight or lifting your eyebrows with confusion, I must say that this is the potential. I mean, you could, but…. When you were born, you had everything you needed to see colors. Newborns see only in black and white. The brain must learn how colors work. How to interpret electrical impulses through the optic nerve to know which one represents a certain color.
And then to paint some beautiful pictures. The job of an artist. Every child teaches himself to sing. The difference between this and singing is that no one sees what you see. You have no idea if the person sitting next to you sees the same things in more or less shades than you do. Or maybe his colors are more vivid or darker. Or perhaps the color accent is more red , or green , or blue.
Or maybe his mind receives very similar signals, but interprets them differently. It is a sight disorder that makes the shades of red look something like those of green. Those who have only two types of cones or those whose third cone is like non-existent, is called dicromatism. What do you think happens to the number of colors? You have a red wire and a green wire. You just have to cut the red wire.
Do not, by any circumstance, cut the green one! Luckily modern technology rescues you. You take a picture and you know what wire has to be cut. In cases where the cones are not completely missing, but behave abnormally to some extent, the brain can be helped with special glasses that change the shades that can not be visibly seen without them. There are also cases, pretty rare indeed, when some people do not perceive colors at all.
Everything they see is black and white, like an old television. Their view is called monocromatism. Try to remember that when you look at a flower garden. Or at a rainbow. Did it ever seem to you that women have a greater proclivity for color?
From what was said above, you can draw the conclusion that, on average, it is correct. You know, superheroes have all sorts of incredible superpowers. It excites you, they seem like fantasies. For example, what would someone with the superpower of seeing times more shades be like?
With the ability to see each surface more colorfully detailed? With a new understanding of space through color? Such people do exist. In fact, they are only women. I told you that women and colors have a special relationship. This is what physicians call tetracromatism. The implications can be major. As you know, it is sufficient to complete the formula for calculating the number of colors that can be distinguished:.
These details give the brain more information to better estimate distances, forms, movements, etc. In fact, there are 4 dimensions, but chromatic. In cases found so far, this fourth type of spectral cone is inserted between red and green. Usually corresponds to a kind of orange. In some cases, additional cones collected frequencies very close to red , or green.
Concetta Antico was a little Australian girl with talent in painting; this is when she realized that her view was different than others. But it differed in a way that was useful to her talent. So she made her artistic abilities into her career. Two decades passed before she learned in that her eyes have 4 types of cones. In her paintings, she tries to represent what she sees — and the result is very interesting.
And 10 million different shades of light affect those 10 million colors. And so do 10 million surrounding colors. Plus, every individual sees colors differently. Facebook Twitter Email.
Ask Clay: So just how many colors are there?
