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. We are in class now, and photography is the three primary colors RGB (red, green, and blue).

In addition, the phosphor of the TV we watched is also this combination. You can see the CRT in front of the color TV, but don't look at the monitor of the computer in front of you. His pixel is too small to be discerned by the naked eye. The combination of the three colors of RGB forms almost all colors.
