tilthat: TIL a philosophy riddle from 1688 was recently solved. If a man born blind can feel the differences between shapes such as spheres and cubes, could he, if given the ability, distinguish those objects by sight alone? In 2003 five people had their sight restored though surgery, and, no they could not.
nentuaby: I love when apparently Deep questions turn out to have clear empirical answers.
I think yes. Light is a wavelength, so whatever colours we are seeing are in ratio to one another. There might be some perpetual variation due to the quality of our eyes - but red orange and yellow are next to each other on the spectrum.
Nobody will see that any differently.
Unless your eyes are the ones converting the wavelengths, then it still is not sure to be the same with everyone.
We could flip the colour spectrum and all the colours that should be next to one another still are.
