Why is it multiplicative? I didn't quite understand that part.


hardware uses RGB, right? how does it convert between different models?


"The CMYK model works by partially or entirely masking colors on a lighter, usually white, background. The ink reduces the light that would otherwise be reflected. Such a model is called subtractive because inks "subtract" the colors red, green and blue from white light. White light minus red leaves cyan, white light minus green leaves magenta, and white light minus blue leaves yellow"- from Wikipedia

dont understand why its multiplicative
