how do we know if we perceive colours the same way?
In: 19
We don’t know, and it doesn’t matter anyway. The only thing that matters is that we have the same spectrum of visible light.
It is the same as sounds. Whether or not we perceive sounds the same way, as long as we perceive them nothing changes.
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.

there are apparently a number of people who have their red/green colour perceptions switched. this happens because two forms of red/green colours blindness occur in the same person, swapping the red/green sensors.
however, they do not know they’ve got this condition. we only know how many people must have the condition, no one appears to have reported symptoms of it.

I don’t know if Tommy Edison is still active on Youtube, but he had an old video where he talked about the different ways people have tried to describe color to him. He’s blind since birth, so he has no experience seeing color whatsoever, but he knows what all the different colors are and what they represent. He knows that the sky is blue and so is the ocean, even if water is clear, he knows trees and grass are green unless they’re dead then they’re brown or yellow, he knows fire trucks are red and school buses are yellow, and so on. But he’s never been able to “imagine” color. No one’s ever been able to describe what green looks like, they can only name objects that are green.
