Generic question about Eyes and Colours?

What are your thought on the following? You need to disregard the fact that science may have already dis-proven this theory but I was just thinking about this today.

We assume that we all see colours the same way; but who's to say that the colour black to me doesn't appear as the colour pink to you etc. If we see the same colours differently we will still think they are the same because you'd be brought up thinking the colour pink (which is black to me) is in fact pink.

The only time it might be obvious that we are seeing different colours is if you're designing something and ask me which colour would look best. Let's say it was something where a dark colour would look best so I say black (which is pink to you). This might reveal the fact that we are seeing different colours as in your view that's a light colour (pink) but in my view it's a dark colour (black).

At the same time however you would be seeing pink where I see black so in your world there would be a lot of pink meaning that you have a tendency to favour black given it's a dominant colour in your world - hence my suggestion might be accepted and not debated.

What are your thoughts?

Update:

Thanks for trying to respond guys but so far you've misunderstood what I'm saying.

What I'm saying is that we've all learnt colours by being shown colour swatches and being told "this is black" or "this is pink" etc. Although we see the colour who's to say that the colours don't appear differently to me and you.

Ok a carrot is orange but what if the colour orange appears to me as the colour green and vice versa. So in other words everything orange looks green in my world and everything green looks orange in my world. We would see different colours but we would refer to them in the exact same way because I would think the colour green (which is what carrots look like in my example) is named "orange". The sun would look green to me too however I'd know it's the colour orange. No-one would really question it as it would fit in with the conventional naming of colours.

We can't really describe colours except for "red makes me feel angry", "blue makes me feel cold" etc. so I find t

Update 2:

...the question to be quite interesting.

I'm not saying that this theory is correct. I tend to disagree with it but I thought about it today and thought it would be interesting to get some different opinions.

Update 3:

Touché U V. Good call about the Black. I wasn't even thinking about that when I wrote the question :) Thanks for your answer.

    [General..] you are TOTALLY RIGHT.

    Colour is a PERCEPTION.. it is not real... infact, our rods and cones detect light as ENERGY... magnitudes of energy (photons)... E = hf and then converts this energy to electrical impulse and sends that to the brain.

    Now the brain assigns a certain 'colour' to that energy... and so we get a 'colourful' picture to differentiate different energies.

    But as for your interpretation of BLACK... black is not a colour... it's the ABSENCE of light. Now in absence of light, the receptors don't send any signal to the brain... and so the brain also assigns a 'colour' to represent no energy or no signal. Now it's easy to say that if you close your eyes and sleep... or go unconcious or die, your brain is not receiving any signal, or not even funtioning... then that 'assigned colour' will be BLACK... now since death = no perception, which is the same for everyone, it's SAFE to say that everyone 'sees' black as the SAME colour.

    That is, the brain doesn't assign any colour to 'black'... black looks the same for everyone.

    But for all other 'colours'.. you're right.. .my red apple could appear to your green apple.

    ...what? Except for colorblind people, we all see the same colors and call them the same thing. If you asked five people to tell you what color the dress was you described above, they wouldn't all say different colors. They would all call it pink.. not black. We all see the same colors, because we all have the universal truth that carrots are orange, apples are red and green, strawberries are red. You know, stuff like that.

    Interesting thing to think about, but you forgot the obvious facts.

    I think this is flawed...
