Fun color-theory fact for those not familiar: the print primary colors are the inverse of the light primary colors. Cyan is white without red (#00FFFF), magenta is white without green (#FF00FF), and yellow is white without blue (#FFFF00). We use these colors because pigment absorbs different wavelengths of light, so we start with white and absorb (i.e.subtract) different amounts of red, green, and blue (the components of human eye-sight) instead of starting with black and adding them! As an added bonus fact, black is all of the pigments at the same time, so we can just add black ink to the lowest of all three numbers then add up as needed. The actual math is waaaaaay more complicated because sight, pigment, and light are are bananas more complicated, but that's the gist.
