I have always found describing color shades interesting/mind-fuck. Does the "red" that you see "red" to me? I am red-green color blind and a lot of "red" looks "brown" to me.
- xwdv 7y agoColor doesn’t actually exist. We don’t see actual objects as they are, we see the light that bounces off of them. Brains will create their own way of mapping wavelengths to colors, so therefore we do not see the same thing, but we perceive it as the same. If I opened your brain and swapped your red with blue, you would not notice.
- gatherhunterer 7y agoColor does exist. The wavelength of light that is reflected by an object is its color. That wavelength can be measured objectively.
- kube-system 7y agoYou’re pointing out that wavelengths exist. The relationship between wavelength and color is not a universally shared experience.
- BurningFrog 7y agoYeah, but all real light is a mixture of a lot of wavelengths that our retinas filter down to three aggregates of "red", "blue", and "green".
- jbay808 7y agoYes, it's kind of like wondering "Does my computer store [R,G,B]? Or is it actually stored as [B,G,R] in memory? Are they represented in 2's complement form?", etc. Functionally our perception of colour is just how we mentally represent and compare vectors with 3 (or in this case 4!) components. That said, our shared physiology and biology as humans makes my default assumption that red looks about the same to me as to anyone else. Unless they're colourblind or tetrachromats, of course.
- aasasd 7y agoIf you want to dig deep, that's a textbook example of qualia: https://en.wikipedia.org/wiki/Qualia https://en.wikipedia.org/wiki/Qualia and https://en.wikipedia.org/wiki/Knowledge_argument https://en.wikipedia.org/wiki/Knowledge_argument (Though I can't quite agree with Jackson that qualia refutes physicalism.)
