  the brain’s actually trying to understand what things are made of, and it’s guessing at that based on the light that enteres the eye.

  this is why when you pick up a thing outside and take it inside, it doesnt change color (edge cases exist), even though the light that reflects off of it into your eye absolutely changes a lot.

  That doesn’t make them fake, in the same way that x can mean 2. You are merely representing a given value in a useful way.

    But is my red the same as your red? Hmmm?

      if two people can both point to red and agree that it’s red, that’s close enough. anything beyond that is just pointless esoteric debate.

        I disagree that it’s pointless. I think it may be beneficial to humanity (eventually) to establish whether or not there is an objective reality which we all experience.

        It was a joke?

        Some people see numbers instead/along with colors, and different people see different numbers, so I guess the colors might be different between people too

    I hadn’t thought about it that way.

    Pink isn’t real. There is no wavelength of light that is pink.

      Its bright red, maybe toward purple! Brown is dark orange.

        Light frequencies between blue and red don’t exist.

      Clearly, it’s light-ish red.

        For pink light to be perceived, it needs red cones to fully react, and both green and blue cones to only partially activate.
