Some consider white to be a colour, because white light comprises all hues on the visible light spectrum. And many do consider black to be a colour, because you combine other pigments to create it on paper. But in a technical sense, black and white are not colours, they're shades. They augment colours.
If color is solely the way physics describes it, the visible spectrum of light waves, then black and white are outcasts and don't count as true, physical colors. Colors like white and pink are not present in the spectrum because they are the result of our eyes' mixing wavelengths of light.
White light is a combination of all colors in the color spectrum. It has all the colors of the rainbow. Combining primary colors of light like red, blue, and green creates secondary colors: yellow, cyan, and magenta. All other colors can be broken down into different combinations of the three primary colors.
White isn't a primary, secondary, or tertiary color. Scientifically speaking, it's actually the combination of all colors in the visible spectrum of light.
In science, black is the absence of light. And color is a phenomenon of light. But a black object or black images printed on white paper are made from pigment, not light. So artists must use their darkest color of paint to approximate black.
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.
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.
It's been described as elegant, classic and timeless – a universal colour because it can work in virtually any room of your home.
White is the lightest possible color.
Primary Colors: The primary colors are red, yellow, and blue. These colors are considered pure because they cannot be made from any other colors.
It has been determined by people who determine such things that there are somewhere around 18 decillion varieties of colors available for your viewing enjoyment. That's an 18 followed by 33 zeros.
Grey (more common in British English) or gray (more common in American English) is an intermediate color between black and white. It is a neutral or achromatic color, meaning literally that it is "without color", because it can be composed of black and white.
If colours were simply a naming scheme for wavelengths then pink is not one, because it is made up of more than one wavelength (it's actually a mix of red and purple light). If you took a laser and tuned it across the visible wavelengths, from infrared through to ultraviolet, you would not pass pink on the way.
In physics, a color is visible light with a specific wavelength. Black and white are not colors because they do not have specific wavelengths. Instead, white light contains all wavelengths of visible light. Black, on the other hand, is the absence of 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 or painting, brown is usually made by combining the colors orange and black.
This is because a rainbow is created by light passing through water droplets. The light that comes from the sun seems white to us. But the white light we see in everyday life is actually made up of a mix of different colors.
According to the the opponent process theory, there is no color that could be described as a mixture of opponent colors. The same way you can't have a number that's both positive and negative, you can't have a color that's red-green or yellow-blue. These are impossible colors.
Black never fails to make you look slim and elegant. Darker shades of colors like blue, purple and brown can also help to hide flaws and create a slimming illusion. On the other hand, lighter colors, like white and khaki, can add pounds and give the illusion of a larger frame.
Blue. Blue is perhaps the best color for your bedroom. Not only is it more muted, but blue tones also tend to have more calming effects on the brain, as shown in a 2018 study of blue walls in a university residence hall.
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.
1. Lapis Lazuli. Lapus Lazuli is a blue mineral so rare that in the Middle Ages and the Renaissance it was actually more valuable than gold.
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.
Legendary is a soft, gray, millennial beige with a silvery undertone. It is a perfect paint color for a living room or exterior home.
Now, due to antagonistic fashion in which colours work and the opponent process, we can't see certain colours at the same time, i.e. blue versus yellow, red versus green, and light versus dark. The colours blueish-yellow and greenish-red are the alleged “impossible” colours we can't see.
