    In terms of color mixing principle, it is generally divided into optical tricolor (following the principle of color addition) and printing tricolor (following the principle of color subtraction) The combination of optical tricolor: red, green and blue: Red + Green = yellow; green + blue = cyan; red + blue = magenta; Red + Green + blue = white The colors written here are all 100% color overlay With the difference of their superposition proportion, different colors will be produced Printing three primary colors: cyan, magenta and yellow combined colors: cyan + magenta = blue; magenta + yellow = red; Yellow + cyan = green; cyan + Yellow + magenta = black The colors written here are all 100% color overlay As they stack in different proportions, they produce different colors Because printing produces color by the principle of ink reflecting light, the purity of the color reflected has a lot to do with the ink used In particular, it is impossible to achieve pure black when green yellow is superimposed into black in practical application, so a black will be added to the printing to form green yellow black four colors Television and display are the three primary colors of optical principle Color is produced by superposition of different amounts of three colors Books, posters and other printed materials are produced by the subtraction principle of color Because the color in optics is different from that in printing, the color range (gamut) they express is also different Generally speaking, the gamut in optics includes the gamut in printing That's why the color of printed matter sometimes can't reach the color displayed on the monitor or TV Another: among the three colors of printing, cyan refers to the sky blue, magenta refers to the magenta and rose red In the early printing factories, the common workers were called blue and red So that's why the three colors of printing are red, yellow and blue This is confused with the optical red, green and blue So we must pay attention to this.
