Many of us are colour blind which confirms we're definitely not all perceiving the same thing...

Depends on how their brains process the colors. Basically what parent commenter is saying, is the color systems we use do not cover the entire gamut of visible light.Visualization of this: https:&#

I believe both of you :) Human color perception is weird like that.

We don't even perceive colors the same way.

A moment where we can all learn from those with blue/green color vision deficiency. Who sees the world more accurately in this context?

Wow - sounds like you have more sensitive than average color perception.Do you think you might be a tetrachromat?

That is getting out of topic fast, but have you checked for blue/green color blindness? This one is not widely tested, come in several different forms, and the most usual "symptom" is that you disagree with everybody about colors being more blueish, greenish, purpleish and etc.It also doesn't impact much one's life... unless you have to read resistor values every day.

It's not that you wouldn't see the difference between sky and grass, it's just that you'd classify it all as a different shades of the same color, as it's closer to it than to say red. On the other hand yellow would p

As I understand it, it isn't that people don't "see" the colors if they aren't defined but that they haven't learned to distinguish between them. A similar example might be cars. I have a 2009 Honda Fit (Jazz in some parts of the world). To most people, a Fit is a Fit but because I have one, I can tell the difference between the first second and third generation just by glancing at them. If I point out the differences, someone will see them but they don't seem
