Comment on Why is #FFFFFF white, but mixing red green and blue paint is black?

  As opposed to the posters and paintings that shine, huh? Wtf are you on about? Those are all like print in that they mix pigments that absorb light. That’s exactly what over_clox said. The contrast is with monitors or displays that emit light, like phones or computer screens.

    They’re all subtractive in print.

    The person said RGB is additive. Where in print is RGB additive?

      You don’t use rgb in print.

  Yes, I said CMYK print is subtractive, did you read my comment?

    You’re close to getting it. You said RGB is additive. Where in print is RGB additive?

      Hey dude, is everything okay? It’s just the Internet and just a discussion about printing and colours.

      Quick crash course, we’re gonna ignore K for simplicity, and assume a basic RGB system. Okay, simplest conversion to CMY is…

      C=1-R
      M=1-G
      Y=1-B
      

      I’m totally skipping over a lot of stuff here, but this is about the simplest conversion for example sake.
