how do we know if we perceive colours the same way?
In: 19
well, theirs two ways to look at this:
the science answer: Coloured light as a specific wavelength, so for someone to see “green” they would need to receive light with that wavelength.
the philosophical answer: does it matter? as long as two people look at (say) a plant and can agree “that plant has green leaves and a white flower”, then the percieved colours are almost irrelevant so long as they are consistent.
