    isn’t there a difference between pigment/light and how it is interperted?. Like isn’t black the absent of color. White is all the bands of light at once while pigment black is all the colors at once but yet it is not the blackest of all blacks so they don’t even make black that way.

      Yeah, additive vs subtractive color. Our eyes see light but light is reflected by pigment.

      Pigment determines which colors are subtracted from light, so combining all pigments gives you black (little to no light reflected) (edit: this is also somewhat of a simplification, it can be more complicated than that). But combining different colors of light gives you white, if nothing is being absorbed.

      Now whether the absence of color still counts as a color in and of itself in either system, I would still argue yes. Color is just our perception of light frequencies or lack thereof, so it’s all subjective anyways.

        To further this, this is why your monitor uses RGB, but printers use CMY (+K but technically you could get away with just CMY) Cyan absorbs red light, only reflecting red and green, magenta absorbs green light, only reflecting red and blue, and I’m sure you can guess what yellow absorbs. Your monitor on the other hand isn’t reflecting exterior light, it’s creating its own.
