The three primary colors are red, green and blue. After mixing, the brightness will be higher. When mixed in equal proportions, it will be white, so it is called an additive color system. The roof is called Mihara Hikari The subtractive color system is unfamiliar to CyanMagentaYellowblacK. The three primary colors are cyan, magenta, and yellow. RGB is subtracted from white in sequence, so it is called a subtractive color system. If you had studied art well in elementary school and junior high school, you would not have called the three primary colors of the subtractive color system red, yellow, and blue. The subtractive color system based on absorption spectrum superposition is suitable for traditional prints and various art works Obviously, these six colors are 31 36 in ANSI. Because the computer screen actively emits light, it uses the RGB system, while traditional printed matter has always used the CYMK system. At this point, if anyone still doesn’t understand why there is no orange color, then Additive color system color palette. The left side is a dark color. For convenience, just use the background color. The right side is a bright color. The following transparent colors are based on the additive color system. They are actually light mixing. Pure equations 128 128 255 The following transparent colors are also based on the additive color system The brightness of the mixed areas on the left has not been adjusted up. It looks dark. It is more versatile. The ones on the right are very bright, giving people a strong feeling of light and shadow, which is consistent with the additive color equation of light mixing. The following transparent colors are based on the subtractive color system and are the effects of mixing two pigments. Like color blocks painted on canvas, commonly used Note that the mixed part in the middle is high-gloss gray instead of low-gloss white. The final reminder is that half of the high-gloss white is high-gloss gray This is the reason for the color reduction above In the RGB system, the three subtractive primary colors mixed together cannot achieve pure black but gray. Because it’s always shining. No matter how much you mix, there’s still light. So CYM needs to add a blacK to determine the grayscale In the traditional printing industry, K is due to issues with materials and pigments.
