There are two kinds of colors we see in our daily life, one is the light emitted by the object itself, such as the sun, red and green lights, car tail lights, and the other is the one that does not emit light itself, such as green leaves and flowers, clothes, these colors are reflected by the sunlight into our eyes, the color that emits itself is called RGB color, there are three kinds of red, green and blue, they can be composed of 16.7 million colors, and directly from the When sunlight shines on an object, part of the light source is absorbed by the object, and the other part is reflected to the eyes, so visually the color is not as bright as RGB.
The ink used for printing cannot be luminous, and the pre-press file is also CMYK. When we put the file on the cell phone or computer, what we see is actually RGB color.
