: how are we sure that we all see the same colors ?

Question

I’m not sure how should I phrase it but lets give it a try.

How are we sure that the color I see as green, for exemple, is the same color as someone else’s green?

Is it possible that the color I call green is an other color for someone else’s eyes but we name it the same because we grew up with people naming this color “green”?
I really hope im being clear enough

We don’t. You’re talking about something known as qualia. We can’t know what someone else’s subjective experiences are.

We know that for the most part we all agree what red is, what blue is, etc but we can’t, and most likely never will, be able to know how other people experience that.

Now have fun when people come in and misinterpret your question and start talking about wavelengths of light, etc.
