dodamaksoud, I know what you mean essentially how can anyone prove that the green they see is the same green that others see? First the physics of it, the wavelength of a colour is the same regardless of what is receiving it, ie in this case the eye. So what the eye and brain of the observer translate it too will always be known as the colour concerned to that observer and yes I have often wondered if my green is the same as your green or indeed whether it's completely different, I mean my green could look more like my yellow to you once your brain has translated it even though it's the same wave length. It may explain why people have a different opinion about what colours go together. The short answer is how could anyone know?
Does it matter?
Yellow is yellow, regardless of how it is percieved. Even if I see yellow as what you see as yellow, the yellow would still be yellow to both of us. How on earth could you test this?
There is no hardcore proof for us to prove you wrong, there's no proof to prove you right. It's just a mildly diverting philisophical doodad, like that "if a tree falls and noone is around to hear it" thing.
You're right, doda, it's subjective. No-one could possibly know what you perceive. As an example, if you were hypnotised and assured that bananas had all turned dayglo pink, that's what you'd see. You'd be trying to explain to everyone that those bananas on the table in front of you had suddenly turned dayglo pink, and they wouldn' t be able to convince you otherwise. You'd find it very bizarre, but you'd still see dayglo pink bananas.
What happens in your brain is an entirely separate issue from what happens in the outside world. Regardless of the frequency of the light particles/waves that are striking your retina, you'd 'see' (perceive) what you'd been told to see. So, would everyone else think it strange that the bananas didn' t look pink to them? Of course not, they'd just accept that they and you were perceiving the colour differently. And who's to say we're not all doing that all the time??
I think we all generally see the same colours but we see different shades to it. There's always to argument over something turqouise where some people say it's green and some blue. And then there are the colourblind they see things differently too.
It must be the same as it is for taste. See if I drink a glass of redwine I taste maybe 3-5 different things whereas Jilly Goolden would taste a summersday in Morroco when a man has just walked past with some cinnamon swirls
