Share
RGB is a color standard in the industry, which is used to obtain a variety of colors by changing the three color channels red (R), green (G) and blue (B) and superimposing them on each other. RGB represents the color channels red, green and blue, and this standard includes almost all colors perceived by human vision. It is one of the most widely used color systems.
