Apparently not: turns out there are six colors that you can see that don't exist. Firstly, let's get it out of the way … technically, magenta doesn't exist. There's no wavelength of light that corresponds to that particular color; it's simply a construct of our brain of a color that is a combination of blue and red.

So how do we know there are 18 decillion colors? First of all, scientists have determined that in the lab we can see about 1,000 levels of dark-light and about 100 levels each of red-green and yellow-blue. So that's about 10 million colors right there.
We see our world in a huge variety of colour. However, there are other “colours” that our eyes can't see, beyond red and violet, they are: infrared and ultraviolet. Comparing these pictures, taken in these three “types of light”, the rainbow appears to extend far beyond the visible light.
Brown is a color. It can be considered a composite color, but it is mainly a darker shade of orange. In the CMYK color model used in printing and painting, brown is usually made by combining the colors orange and black.
Black is not a color; a black object absorbs all the colors of the visible spectrum and reflects none of them to the eyes. The grey area about black: A black object may look black, but, technically, it may still be reflecting some light.
And many do consider black to be a color, because you combine other pigments to create it on paper. But in a technical sense, black and white are not colors, they're shades. They augment colors. “And yet they do function like colors.
A healthy human eye has three types of cone cells, each of which can register about 100 different colour shades, therefore most researchers ballpark the number of colours we can distinguish at around a million.
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.
While those of us with three of these receptors – called cone cells – have the ability to distinguish around one million different colours, tetrachromats see an estimated 100 million.
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.
In the living world beneath our red-ravenous atmosphere, blue is the rarest color: There is no naturally occurring true blue pigment in nature.
Find out which colors are the world's favorite and the least liked. The most popular color in the world is blue. The second favorite colors are red and green, followed by orange, brown and purple. Yellow is the least favorite color, preferred by only five percent of people.
Today researchers use physics to invent new colours, inspired perhaps by the iridescent shades created by structures in butterfly wings that scatter light. These new structural colours are the result of an interaction between light and nanoscale features many times thinner than human hair.
For tens of thousands of years, humans have created colours through simple chemistry. At first we used dyes found in nature such as berries and charcoal. Later, new pigments were synthesised in the lab.
Primary colors include yellow, blue, and red. These are colors that can't be created by mixing of other colors. Instead, they combine to create secondary colors, which in turn combine to create tertiary colors. In effect, all colors stem from the three primaries.
Here are OSHA's recommendations for the color of signs: Red = Danger. OSHA recommends danger signs or tags be red or predominantly red, with lettering or symbols in a contrasting color (usually white against the red background). Red warns of a hazard that could cause serious injury or death.
In fact, Queen Elizabeth I forbad anyone except close members of the royal family to wear it. Purple's elite status stems from the rarity and cost of the dye originally used to produce it. Purple fabric used to be so outrageously expensive that only rulers could afford it.
While we can see 100% of the visible spectrum – not 1% – we see very little of the total electromagnetic spectrum. And that share is even less than 1%. Light visible to humans makes up just 0.0035% of the electromagnetic spectrum. Other animals can see more than visible light.
The entire rainbow of radiation observable to the human eye only makes up a tiny portion of the electromagnetic spectrum – about 0.0035 percent.
The human eye can discriminate up to ten million colors, and since the gamut of a display is smaller than the range of human vision, this means this should cover that range with more detail than can be perceived.
It's true that "plain white" paint does exist. You can ask a paint store to give you the purest white paint they have, and you will get it. This paint will be bright and almost unbearably white, and you may not actually like it after all.
Black hair is the darkest and most common of all human hair colors globally, due to larger populations with this trait. Black hair can be found in people of all backgrounds and ethnicities. Black hair contains a large amount of eumelanin pigmentation, a type of melanin.
White light is a combination of all colors in the color spectrum.
