Week 5 - muddiest point

I'm curious as to why image coding uses red, green, and blue, rather than the traditional primary colors red, blue, and yellow.

  1. Red, Green, and Blue are the primary additive colors, that is, they are the three primary colors used for mixing light. Green + Red light = Yellow light.
    The Red, Yellow, Blue model is used only with pigmentation, and it is subtractive, the rules which apply to combining and mixing different colors of pigmentation are different than rules governing colors with regards to lightwaves.
