Are there colors that we CAN'T see?

The human eye has three types of cone photoreceptors; Blue, Red and Green The other colours that humans perceive like yellow, purple or the color of the absence of objective purpose of life are Just a combination of those three main ones. But what about other colors that humans can't see? Do they even exist and if so, what would everything look like? Light It is made up of photons and waves, at the same time. Also time doesn't exist from its perspective. (More on that in this video) Light can be

of different wavelengths from radio waves the size of football fields, to gamma rays the size of atomic nuclei. Meanwhile the human eye can see only this small fraction called the visible light. Everything else is just invisible to humans. You can make an experiment yourself, right now. Take your TV remote and look at its front through a phone camera. Press any buttons on the remote and the LED will start to glow, but only on the camera. This happens because the light emitted by the TV remote i

s an infrared wavelength. The human eye can't see it, however the camera allows a small fraction of the infrared light to pass. Why did the human eyes evolved to see only visible light though? It is because of our sun. It shines mainly in the visible light spectrum. If it were more prominent in X-Ray light we would have evolved see X-Ray Therefore, the answer is yes. There are a lot of colors that humans can't see, so let's hypothetically assume that you could perceive absolutely all the wavelen

gths of light, at the same time, how will the world look? Take shrooms for a close approximation. Just kidding, do not. First of all, you'd probably go insane. Everything that is warm or hot will be glowing. When you turn in your microwave it would glow, too. You would see lots of waves coming to, and from your phone. Oh, and also Wi-Fi. Everything would be covered in weird, radio rainbows. Radio towers would be pretty much lighthouses, and the sky, because of the stars, it would always glow. Yo

u could also use uranium ores, as lamps. Although I do not highly recommend it. This is a shrimp. A mantis shrimp. It is really badass. Apart from the fact that they can throw a punch with the acceleration of a bullet, they also have sixteen photoreceptors, compared to ours three. That's hell of a lot more colours. That allows them to see ultraviolet, polarized and visible light. They can also perceive depth with each individual eye. But what if I told you that you can see colors that are in rea

lity not possible. These are called impossible colors, and they come in pairs of green and red, yellow and blue and white and black. But you may ask, 'why are these impossible?'. Isn't yellow and blue, green red and green, some kind of brown and white, and black, grey? The cells responsible for processing the electrical signals from the cones are called opponent neurons. There are two types of them. Red, green and blue yellow. They can only receive only one colour, so when you look at something

red the green receptors are inhibited. Alternatively, when you look at something green, the red ones are inhibited. And that is why you can't perceive a red green or blue yellow colour. But you actually can. If you look at a part red, part green image for long enough, your photoreceptors will go batshit. So here's the experiment: Take a look at this image and look in the center without moving your eyes for around a minute. The color should blend together to form an impossible colour. Try it. Pau

se now. Also, try this one although, it's a bit harder. It works for around seven out of ten people ,if it didn't work for you. :( I'm sorry, your eyes are broken. Also, look at these cool illusions. Look at the first square for around ten seconds and then switch to the second one. After all, it might be a bit sad that humans do not have 16 photoreceptors like the mantis shrimp. But at least you have something else; like the brain. Or the internet. Or Witcher.
