How do you know if the way red looks to you looks the same to everyone else?

Question

Based on a response, let me elaborate further. Yes, we all clearly agree on "red" and if you were to ask someone, they would tell you something is red and a million others would agree. However, red is just a label for something, how do you know that what one perceives as true red, doesn't look "green" to someone else but they have simply labelled it red. I am not talking about color blind people here.

Answer 1

This is a question I have pondered myself. Although the question I would pose is not so much,"does red look green in another's eyes" but, why when I see burgandy, do others describe it as red....or a colour that is obviously purple, as blue. The answer, in part, I have discovered can be split along gender lines. Apparently, males have a slightly different sense of sight then do women, they see less subtulaties in colour range. To them a red is not more blue, yellow, green (in composition), it is red...therefore burgundy is often described as red..or purple. I cannot believe that this, though scientific, holds true for all men, as some exhibit a highly devoloped sense of colour subtalty. But suffice it to say that is a partial explaination. As for the "red or green" question, I would say this may be summed up in the fact that colour is simply a reflection of light, divided into it's wavelegnth components. When in complete working order, our eyes percieve these wavelegnths in a certian way (as is held out in the fact that groups of people throughout history have differenciated colours, without them having first been labeled....ie some apples are red, some are green and people can tell the difference etc..) And that is how we know that others percieve that legnth of light wave as "red" rather than the wavelegnth we term "green"
Great question. Hope that, although based mostly in my own thought and experience, this answer has been worthwhile to you.

Answer 2

I'd base it on the fact that our bodies are all basically the same with slight variations. So I'd assume there would also be slight variations in how we perceive color. Although the color spectrum is scientific, so I'm sure they have ways of measuring how we perceive color.

Answer 3

Go to a dress material shop with someone, come out choosing any coloured object keeping to urself the choice. Ask the person to get that for u describing it, see what he brings.

Answer 4

We don't know, and it always intrigues me. It would be really interesting to look at life through another person eyes for a while, just to see how they view the world.

Answer 5

You don't you just must know that the world in the way you perceive it is the only important perception of that world. Your opinion is important only in your perception of the world.

Answer 6
