The rare colour termed 'True Cyan' largely escapes the human eye due to the fact that it is extremely difficult for electronic devices to produce them.
That's because, even though those colors exist, you've probably never seen them. Red-green and yellow-blue are the so-called "forbidden colors." Composed of pairs of hues whose light frequencies automatically cancel each other out in the human eye, they're supposed to be impossible to see simultaneously.
Blue is one of the rarest of colors in nature. Even the few animals and plants that appear blue don't actually contain the color. These vibrant blue organisms have developed some unique features that use the physics of light. First, here's a reminder of why we see blue or any other color.
Green is the rarest eye color in the world, with only 2% of the world's population (and fewer than one out of ten Americans) sporting green peepers, according to the American Academy of Ophthalmology (AAO).
Magenta doesn't exist because it has no wavelength; there's no place for it on the spectrum. The only reason we see it is because our brain doesn't like having green (magenta's complement) between purple and red, so it substitutes a new thing.
By crushing 1.1 billion-year-old rocks found beneath the Sahara Desert, scientists say they have discovered the world's oldest color: bright pink.
Legendary is a soft, gray, millennial beige with a silvery undertone. It is a perfect paint color for a living room or exterior home.
It is said that longest color name is coquelicot with 10 letters.
So why is that? Part of the reason is that there isn't really a true blue colour or pigment in nature and both plants and animals have to perform tricks of the light to appear blue. For plants, blue is achieved by mixing naturally occurring pigments, very much as an artist would mix colours.
By around 30 million years ago, our ancestors had evolved four classes of opsin genes, giving them the ability to see the full-color spectrum of visible light, except for UV. "Gorillas and chimpanzees have human color vision," Yokoyama says. "Or perhaps we should say that humans have gorilla and chimpanzee vision."
YInMn Blue (/jɪnmɪn/; for the chemical symbols Y for yttrium, In for indium, and Mn for manganese), also known as Oregon Blue or Mas Blue, is an inorganic blue pigment that was discovered by Mas Subramanian and his (then) graduate student, Andrew Smith, at Oregon State University in 2009.

The answer is, in all likelihood, no. Color is a perception. We can expand the wavelength range of the radiation that we can detect. Night vision goggles, for example, allow us to detect near infrared radiation, but do not provide a new color.
On this R, G, B spectrum, the maximum amount of any color is 225. Arguably, color doesn't actually exist because it's just an interpretation made by our brains to distinguish different wavelengths from one another.
Digital Lavender, Luscious Red, Sundial, Tranquil Blue and Verdigris are the color names for 2023.
Therefore, the colours 'blueish-yellow' and 'greenish-red' are the alleged “impossible” colours that we can't see.
The earliest life on Earth might have been just as purple as it is green today, a scientist claims. Ancient microbes might have used a molecule other than chlorophyll to harness the Sun's rays, one that gave the organisms a violet hue.

Blue is a very prominent colour on earth. But when it comes to nature, blue is very rare. Less than 1 in 10 plants have blue flowers and far fewer animals are blue.
For those in the past, the concept of the color blue might not have existed at all. Even some cultures today don't see blue in the same way as people in the West. This fact may seem impossible but it's true.
For any pigment to appear blue it needs to absorb red light, which require closely spaced energy levels, found only in molecules that are very complicated and hard for organisms to make.
Fossils can tell us quite a bit about plants and animals that lived millions of years ago, including their size, shape and even a bit about their love life.
Monochromacy (achromatopsia)
Achromatopsia is extremely rare, occuring only in approximately 1 person in 33,000 and its symptoms can make life very difficult.
Dogs' eyes only have 2 types of cones (just 20 percent of the cones in human eyes). Because of this, a dog's color spectrum is limited to shades of gray, brown, yellow and blue. This is called dichromatic vision, which is similar to humans who experience red-green color blindness.
