How do we know we all see the same colours?

How do I know when I see green it is the same as everyone else is seeing. I know its green because I was told its green. How do I know someone else isn’t seeing a different colour, and they were just told that that is green?? We can touch things to tell the difference, but colour is what we’ve been told, we cant touch to tell the difference, or is it??

    before we can swap parts, brain, eyes and nerves on a big scale, doing an accurate study is not feasible, but if the eye receptures are the same in everybody, any difference is limited to the brain and how it interprets the singnals it receives from the eyes.
    the colors are the same to most people’s eyes, to their brains, we can’t be sure.

    In particular, people may not see all the same colors when they look at the same things. These scientists believe that color perception may not be predetermined like many have believed for hundreds of years. … Most people have three different photoreceptors in the backs of their eyes that perceive red, green and blue.

Few years back, you may have imagined about robots dominating the world; a miniature helicopter capturing photos; or living in Mars. Imagination goes well with creation. We’re on our way. For hundreds of years, science has been doing studies and giving explanations to occurrences that go beyond the human imagination and understanding. Thus, theories are created.
For hundreds of years, technology has been doing a great job in industrialising the world. You step in the land of the first world countries and see for yourself how lifestyle has been advancing. Yet, theory is a theory until it’s proven; technology remains limited. You might wake up one day and see that sci-fi turns into reality. However, what happens next when the clock ticks to ‘Midnight’ and doomsday is for the universe?
