How many kinds of colors come out

Yellow and pink are the colors that have colors (two-dimensional).

There are countless colors in nature; However, in computers, colors are composed of red, green, and blue primary colors, and one byte (byte, range is 0 255) is used to represent a color component; So there are 256 256 256 16777216 colors. The so-called 32-bit true color is actually an extra byte of alpha (translucency).

The human eye recognizes colors based on the wavelength of the light they see. Most of the colors in the visible spectrum can be made up of three basic colors mixed in different proportions, and the colors of these three basic colors are red, green, and blue. When these three types of light are mixed in the same proportion and reach a certain intensity, they appear white (white light); If the intensity of all three types of light is zero, it is black (darkness).

Since the intensity of the three types of light is a continuum, it can be said that there are countless colors in the world, but the human eye cannot completely distinguish them.

In general, there is no fixed answer to the number of colors. The number of colors is defined in the color space, depending on the color model we use.

If we use the RGB color model, we can define the color as a value in three-dimensional space. In this case, we can create about 16 million different colors by combining the values of each color channel from 0 to 255. This is because the RGB color model defines a combination of the three colors of a pixel to create almost any kind of color.

However, if we switch to the CMYK color model, we can make a larger range of colors. CMYK color models include cyan, magenta, yellow, and black, and these color combinations can create thousands of different colors. This color model is mainly used for printing because it can produce a wider range of colors and better color accuracy.

There are also HSL and HSV color models, which typically represent colors as hue, saturation, and lightness values. Using these color models, we can produce more different colors; Because we can think of it as a continuous color wheel in the color space, the coloring scheme is created based on the different parametric methods of the grip.

Overall, different color models bring different numbers of colors. But no matter which color model is used, a large number of different colors can be created in general. <>

There are seven main colors and many types of compound colors.

They are: red, orange-red, orange, orange-yellow, yellow, yellow-green, green, blue-green, blue-violet, purple, purple-red. Among them, red, yellow, blue in the color matching in the world high occupies a very important position, they are active in a variety of colors, to maximize the change of each other's brightness, brightness and hue, to produce a multi-level, multi-variety of beautiful colors, so they can not be ignored colorless.
