>>92517141While it's true that in terms of light spectrum every color is its own unique thing, thanks to the construction of the eye we can simulate (almost) all colors using a combination of certain frequencies of light, which we call red, green and blue.
Those are the primary colors of light. When combined, you get the secondary colors of light, cyan (blue+green), magenta (red+blue) and yellow (green+red), and when added all together you get white light. This is the additive model of color.
Meanwhile for tints, inks and other such things, the color comes from the light that is *not* absorbed by the tint, so the relationship is inverted. A yellow tint will absorb blue light, reflecting green and red so you see yellow. When combined with cyan (absorbs red, reflects green and blue), you get blue.
Thus, the primary colors of ink are yellow, magenta and cyan, which combine to make red, green and blue, and all together make blank (no color is reflected). This is the subtractive model of color.
