What are the three primary colors, and what are the three primary colors?

The three primary colors refer to red, green, and blue, and their respective wavelengths are 700nm,,;

Primary colors, also known as primary colors, are the basic colors that are used to mix other colors. Primary colors have the highest color purity, the purest and most vivid. Most colors can be blended, while other colors cannot be blended to create three primary colors.

The three primary colors are usually divided into two categories, one is the three primary colors of color and light, and the other is the three primary colors of pigments, but in art, red, yellow, and blue are defined as the three primary colors of color. However, magenta with a small amount of yellow can make a large red (red = m100 + y100), but a large red cannot call up magenta; Blue can be obtained by adding a small amount of magenta (blue = c100 + m100), while blue and green can get a non-vivid blue; Yellow, magenta, and cyan can be used to create more colors, and they are pure and vivid. The green (green = y100 + c100) is more pure and vivid than the green mixed with blue and yellow, while the latter is darker. The purple produced by magenta and cyan is very pure (purple = c20 + m80), while red and blue can only get gray violet and so on.

In addition, judging from the mixing of other colors, yellow, magenta, and blue are used as their primary colors, and the colors are richer and the colors are more pure and vivid.

To sum up, whether it is from the definition of primary colors or verified by the results of practical application, it is enough to show that yellow, magenta, and cyan are called the three primary colors, which is more appropriate than red, green, and blue.

The three primary colors are the three basic colors that can no longer be decomposed in the color, the three basic colors can be mixed arbitrarily to produce other colors, the three primary colors are divided into the three primary colors of color and light and the three primary colors of pigment, and the three primary colors of color and light are the three primary colors of red, green and blue with equal amounts of color and light, mixed into white; The three primary colors of pigment are yellow, magenta, and cyan (sky blue), and the three primary colors of pigment are mixed into black with equal amounts.

Three primary colors. Including color three primary colors and optical three primary colors, the color three primary colors are magenta.

Yellow, blue, and the three primary colors of color can be mixed to create the color of all pigments, and at the same time add up to black, black, white and gray belong to the colorless system. The three primary colors of optics are red, green, and blue. After the three primary colors of optics are mixed, the display color of the display screen is formed, and the three primary colors are added together to become white, and white belongs to one of the achromatic systems.

The three primary colors refer to the three basic colors that can no longer be decomposed in the color, and we usually say the three primary colors, namely magenta, yellow, and cyan (it is cyan not blue, and blue is the color of magenta and cyan mixture). The three primary colors can be mixed to create all the colors, and at the same time they are added to black, and black, white, and gray belong to the colorless system.

Optical trichromatic: also known as RGB color model.

Or red-green-blue color model, which is an additive color model that adds the color light of the three primary colors of red (red), green (green), and blue (blue) in different proportions to produce a variety of color light.

Pigment three primary colors: ink blending for color printing, the principle and production of color **, color printer design and practical application, are yellow, magenta, and blue are the three primary colors. Color printing is printed with yellow, magenta, and blue inks plus black ink, and the printing of four-color printing press is a typical example.

Three primary colors of color TV: color TV.

The screen is coated with three different phosphors, and when the electron beam hits it, one emits red light, one emits green light, and one emits blue light. In the manufacture of phosphor screens, workers use a special method to arrange three phosphors on the phosphor screen alternately little by little. No matter where you take out the fluorescent screen, the next three points must include one point each of red, green, and blue.

Each dot is the size of a needle tip and does not require a magnifying glass.

I can't see it. Because it is small and close together, when it is shining, it is impossible to distinguish the light emitted by each color point with the naked eye, and only the color of the three colors can be seen.

The analysis is as follows:1. Chromaticity table: 1 black and blue, 2 very dark brown, 3 dark brown, 4 brown, 5 light brown, 6 dark gold, 7 gold, 8 light gold, 9 very light gold, 10 lightest gold.

2. Tone table: 1 gray, 2 green, 3 yellow, 4 orange, 5 jujube red, brown red, 6 red, 7 purple, 8 blue.

3. Background color table: 1 red, 2 red, 3 red, 4 red, 5 orange Pikai red, 6 orange, 7 orange yellow, 8 yellow, 9 very light yellow, 10 the lightest yellow. Trembling lead.

The three primary colors are magenta, yellow, and cyan.

1. Red. Red is the color at the end of the low frequency of the visible spectrum of electromagnetic waves, with a frequency range of 380 480thz, corresponding to a wavelength of about 780 620nm in the air. Red is one of the three primary colors of light and the four colors of the mind, similar to the color of fresh blood.

2. Yellow. Yellow is the intermediate frequency part of the visible part of the electromagnetic wave, with a frequency of 505 525 thz (corresponding to the wavelength of 595 570 nm in the air), similar to the color of ripe lemon or sunflower chrysanthemum, and the spectrum is located between orange and green. Yellow gives a pleasant, hopeful and energetic feeling.

3. Cyan. Cyan, the ancient original meaning is blue, but in the painting color, if it is blue mixed with a small amount of green, it is called cyan (one of the three primary colors of subtraction), and it has multiple levels. Similar to the color of jadeite jade.

Application of the three primary colors:

In the visible light spectrum, the human eye is most sensitive to red, green, and blue colors, and the human eye is like a system of three-color receivers, and other colors can be synthesized by red, green, and blue colors in different proportions, which is the principle of three primary colors. The three primary colors are independent of each other, and neither one primary color can be combined by the other two primary colors. The three primary colors of red, green, and blue are added in different proportions to form a mixed color, which is called additive color mixing.

Red, green, yellow, green, blue, cyan, red, blue, bright purple, red, green, blue, white. In addition, red cyan white, green purple white, blue yellow white. Cyan, purple, and yellow are complementary colors of red, green, and blue, respectively.

In addition to additive color mixing, there is also a subtractive color mixing. Subtractive color mixing is to absorb different proportions of the three primary colors to form different colors. Because white is red and cyan, white-green magenta, and white-blue is yellow, cyan, magenta, and yellow are called the three primary colors of pigments.

The color pattern represented by the above additive color mixing three primary colors is called RGB mode, and the color pattern represented by the subtractive color mixing principle is called CMYK mode, and they are widely used in the fields of painting and printing.
