Question: how do you know that the sky is green and we are just colourblind
colour, colourblind, sky

We can study the wavelength of the light. Every colour has a specific wavelength.
We see the sky as blue because it is a short wavelength and is easily scattered by the dust in the air.
If you are colourblind, and see blue as a different colour (this happens inside your head) it will still seem normal to you.
Eye tests will prove if you are colourblind, I have had mine tested and am not colourblind, so confident what I see as blue is really blue.
But, if I eat a banana, does everyone taste the same taste that I do when they eat a banana?

Light hits things and whatever colour it reflects, it gets sent back to our eyes. That’s the colour that we see.
