What if you actually see only three colors?
It sounds pretty crazy, but this is the real truth. It’s all about the fact that we see colors with our eyes and our brain. The retina of our eye contains three types of color sensitive elements, cones. They react to the length of the color wave in one of the three spectral areas, red, green, and blue.
Each cone sends a signal to the brain and it processes these signals and says something like this. Blue is weak and green and red are strong, so I see the color yellow. I feel you still don’t believe me. Well, so let the brain play this funny game with you right now. It is very easy to demonstrate with the help of three light sources. Red, green, and blue. Now I’ll connect them in one point.
What color do you see?
Yellow. At the same time, it is necessary to understand that signals from two spectral colors are coming into our eyes. Red and green.
And it’s only their connection that our brain perceives as the color yellow. These incredible experiments can be used to make the light of the light. This is a very simple, very simple, very simple, very simple. This incredible experiment can be repeated endlessly. Mixing red and blue gives you. You have probably already realized that this is my favorite one. Purple. Red and yellow give the color orange.
Yellow and green are light green. There are tables on where you can see all the variety of shades that are perceived not by our eyes, but by our brain. Now, what do you think?
How many shades can the brain distinguish?
Alas, science gives different figures, from 150 basic colors to 15,000. Some researchers give a figure of several million color variances, depending on different brightness, tone and saturation. And all these statements are just as striking as they are difficult to verify. Because the brain is really very subjective when perceiving color.
Add the emotional state here. It turns out to affect it too. The cultural environment, bringing some amendments. In addition, there are things which are in fact inexplicable. Do you remember there was a viral puzzle on the internet? What color is this dress? Let’s not repeat that and give a more recent example.
What color are these flip-flops?
I see brownish golden and blue color. And you, let me guess, black and blue. Gold and white. The producer of the flip-flops claims that they are black and blue. And who’s right here? Well, no one. After all, everything relating to color is a purely personal matter.
