What is the standard cyan value in RGB mode?

The standard cyan values in RGB mode are 0, 128 and 128.

RGB colors are three primary colors, R stands for red, G stands for green and B stands for blue. Any color that can be seen by the naked eye in nature can be mixed and superimposed with these three colors, so it is also called additive mode.

When color is defined by computer, the values of R, G and B are in the range of 0-255, where 0 means no stimulation and 255 means that the stimulation reaches the maximum. When R, G and B are all 255, white light is synthesized, and when R, G and B are all 0, black light is formed.

When the two colors are superimposed separately, different "C, M, Y" colors will be obtained. . This mode is usually used when displaying color definitions on the display screen. If the image is used for TV, slide show, network and multimedia, RGB mode is usually used.

Extended data

The main purpose of RGB color model is to detect, represent and display images in electronic systems (such as televisions and computers), but it is also used in traditional photography. Before the electronic age, based on human perception of color, RGB color model has a solid theoretical support.

RGB is a device-dependent color space: different devices detect and reproduce specific RGB values differently, because color substances (fluorescent agents or dyes) and their individual response levels to red, green and blue vary from manufacturer to manufacturer, and even the same device has different time.

Nonlinear. Due to gamma correction, the color output intensity on computer display devices is usually not proportional to the R, G and B values in image files. That is, even if the value of 0.5 is very close to half of 0 to 1.0 (full strength);

The light intensity of computer display (0.5, 0.5, 0.5) is usually about 22% of that of display (1.0, 1.0, 1.0), not 50%.

In the schematic diagram of color light additive method and pigment subtractive method, the left picture shows the three primary colors of color light: red, green and blue; The picture on the right shows the three primary colors of pigment: yellow, magenta and cyan.
