The RGB color mode is a color standard in the industry, which is obtained by changing the three color channels of red (R), green (G), and blue (B) and superimposing them on each other. RGB is the color of the three channels of red, green and blue. This standard includes almost all colors that human vision can perceive. It is one of the most widely used color systems.
In a computer, the so-called “how much” of RGB refers to brightness and is represented by an integer. Typically, RGB has 256 levels of brightness, expressed as numbers from 0, 1, 2… up to 255.
Note that although the number is up to 255, 0 is also one of the values, so a total of 256 levels.
