What are the three primary colors, what and what combinations can produce what colors

Three primary colors. The so-called primary color, also known as the primary color, or the primary color, is the basic color 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. In terms of understanding the concept of the three primary colors, we are basically the same as those in the textbooks. The three primary colors are divided into two categories, one is the three primary colors of color and light, which is called the additive color method three primary colors; The other type is the pigment (dye) three primary colors, also known as the subtractive color three primary colors.

The latter is described in the art book.

The mixing of the three primary colors of pigments, also known as subtractive color mixing, is the reduction of light, after the mixing of the two colors, the luminosity is lower than the original luminosity of the two colors, the more colors are combined, the more light is absorbed, and the closer it is to black. Therefore, the more times it is blended, the worse the purity, and the more it loses its simplicity and distinctiveness. The mixture of the three primary pigments, which should theoretically be black, is actually a black cloudy color with very poor purity, and can also be considered a dark gray with very low luminosity.

Magenta and green, yellow and purple, cyan and orange, the mix of colors is close to black.

Art textbooks talk about the use of paint in painting, and the author has seen that most textbooks and books refer to red, yellow, and blue as the three primary colors. However, the situation in art practice and production operations is not consistent with what the textbooks say. The ink blending of color printing, the principle and production of color **, the design and practical application of color printers, 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. In color** imaging, the three emulsion layers are: yellow on the bottom layer, magenta on the middle layer, and cyan on the upper layer.

All brands of color inkjet printers are also printed in yellow, magenta, blue and black ink cartridges. By definition, primary colors should be able to modulate most of the other colors, and none of the other colors can be blended. Art practice has proved that magenta with a small amount of yellow can make a big red, but a big red can't make a magenta; Blue can be obtained by adding a small amount of magenta, while blue and white can get a non-vivid blue; Yellow, magenta, and cyan can be used to create more colors, and they are pure and vivid.

For example, the green of blue and yellow is more pure and vivid than the green of blue and yellow, while the latter is darker. The purple blended by magenta and cyan is very pure, while the red and blue can only get gray purple 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 blue are called the three primary colors, which is more appropriate than red, yellow, and blue.

Red, yellow, blue.

Together with black, it is called a universal color, and it can be matched with any different color system according to different ratios.

Red + Yellow = Orange.

Red + Blue = Purple.

Yellow + Blue = Green.

Red, yellow, blue. Any combination. Basic tones.

Let's go directly to the encyclopedia and see it for yourself.

Pigment three primary colors (CMYK): red, yellow, blue.

The three primary colors refer to the three basic colors that can no longer be decomposed in the color, and the three primary colors we usually talk about are the three primary colors of color and the three primary colors of optics.

Color three primary colors (CMYK): magenta, yellow, cyan (is cyan not blue, blue is a mixture of magenta and cyan), black.

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.

Optical trichromatic primary colors (RGB): red, green, blue. The three primary colors of optics constitute the display color of the display screen, and the three primary colors are added to white at the same time, and black, white and gray are both colorless.

The three primary colors and the three primary colors are actually the same meaning. That is, theoretically, if there are three colors that can be combined into any other color, then these three colors are three primary colors or three primary colors.

In terms of the principle of color mixing, it is generally divided into optical three primary colors (following the principle of color addition) and printing three primary colors (following the principle of color subtraction).

Optical three primary colors: red, green, blue

Combination of colors: red, green, yellow; Green, blue, cyan (cyan); red, blue, magenta; Red, green, blue, white

The colors written here are 100% color overlays. As they are stacked in different proportions, different colors are produced.

Printing three primary colors: cyan, magenta, yellow

Colors of the combination: cyan + magenta = blue; Magenta + Yellow = Red; Yellow + Green = Green; Blue + Yellow + Magenta = Black.

The colors written here are 100% color overlays. As they are stacked in different proportions, different colors are produced. Because printing is the principle of reflecting light from the ink to produce color, so the purity of the reflected color has a lot to do with the ink used, especially the green magenta three colors superimposed into black in practical application can not achieve pure black, so a kind of black will be added to the printing to form a green magenta yellow and black four colors.

Television and display are the three primary colors of optical principles, and colors are produced by the superposition of different amounts of the three colors.

Printed materials such as books and posters are produced using the principle of color subtraction.

Because the color in optics is different from the color differentiation principle in printing, the color range (color gamut) they express is also different, and the color gamut of optics generally includes the color gamut of printing. That's why the color of the print sometimes doesn't match the color shown on a monitor or TV set.

In addition: among the three colors of printing, cyan refers to the general term sky blue, and magenta refers to the general term magenta and rose red. In the early printing houses, the general workers were called blue and red.

So this is the reason why the printing tricolor is: red, yellow and blue. And this is confusing with the red, green, and blue colors of optics.

So be sure to pay attention at this point.

Summary. Knowledge expansion: The three primary colors are red, yellow, and blue, and the three intermediate colors are green, orange, and purple.

Red, yellow, and blue are the three primary colors, and orange, green, and purple are the three colors. Red and yellow turn to orange, red and blue turn purple, and yellow and blue turn green. Red, yellow, and blue are the three primary colors, while orange, purple, and green are the three colors.

Hello, I'm glad to answer for you: dear, the three primary colors are red, yellow, and blue; The three primary colors refer to the three basic colors that can no longer be decomposed in the color, and we usually say that the three primary colors are called magenta, yellow, and blue (it is green not blue, and blue is the color of magenta and trembling blue). 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.

Knowledge expansion: The three primary colors are red, yellow, and blue, and the three colors are green, orange, and purple. Red, yellow, and blue are the three primary colors, and orange, green, and purple are the three colors.

Red and yellow turn to orange, red and blue turn purple, and yellow and blue turn green. Red, yellow, and blue are the three primary colors, while orange, purple, and green are the three colors.

The three primary colors of good afternoon refer to red, closed green, and blue, also known as the RGB three primary colors. These three colors are made up of light, and they can be produced with different brightness and mixing ratios to eliminate a variety of other colors. In electronic devices such as televisions, computer monitors, and mobile phone screens, RGB primary colors are used to display images and**.

In addition, in the printing industry, the three primary colors used are cyan, magenta, and yellow, also known as the CMY three primary colors. The mixing of these colors can produce other colors, such as black. <>

The three primary colors refer to the three colors of red, green, and blue, also known as the RGB primary colors. These three colors are the basic colors that make up the color world, and can be mixed to form various other colors of the color circle. In electronic devices, such as computer monitors and television screens, RGB primary colors (i.e., red, green, and blue) are used to synthesize the desired colors, which is also known as the "additive color method".

In printing technology, CMYK four colors (i.e., cyan, magenta, yellow, and black) are used, which is also known as the "subtractive color method". It should be noted that the three primary colors mentioned here refer to the three primary colors in optics, and the three primary colors in primary school art teaching refer to the three primary colors on the pigment, that is, red, yellow, and blue, rather than the three primary colors on the optical jujube orange.

The three primary colors refer to the three basic colors that can produce various other colors, and they are: red, green, and blue, or RGB for short. These three colors are generated by visible light of different wavelengths, and are defined as three primary colors in the theory of chromatic light trichromatic color.

Using red, green, and blue colors to be stacked or mixed in different proportions, up to 16 million colors and shades of color can be produced. This color mixing method is widely used for color reproduction on TVs, monitors, mobile phone screens, etc. In addition to the three primary colors of color and light, the principle of the three primary colors is also used in painting and printing.

The three primary colors used for printing are cyan, magenta, and yellow, or CMY for short. They are complementary colors of the three primary colors of red, green, and blue, and by adjusting the proportions of these three colors, a wide range of colors can be produced. Many color printers and inkjet printers use CMY's principle of three primary colors to complete color printing.

Therefore, from the perspective of color light and painting, the three primary colors are composed of three basic colors. By combining and superimposing these three colors, all the other colors can be produced. Red, green, and blue are the three primary colors in chromic light and electronic displays, while cyan, magenta, and yellow are the three primary colors in printing and painting.

Understanding the principle of the three primary colors helps us to further understand the principles of color production and reproduction. <>
