Many people ask this question without really realizing what color (or for that matter, vision) is.
Different colors are different frequencies of electromagnetic waves. These waves enter our eye and excite one of three different kinds of receptors. (simplified) We call these short, medium and long cones (S, M, and L stand for relative wavelength) The percentage of each cone stimulated for a given receptive field is sent back into the brain. The concept of “color” does not arise until much later.
We recreate all we see in our brain, we never see “reality”
But back to the point, when people realize they can not describe colors to eachother, they then wonder if we all see the same colors. The truth is that color is really a much different idea than most people have, and wondering is we all see the same colors is kind of a moot point.
It is just as valid of a question as “Is fear the same feeling in everyone?” or “Is my feeling of hungry the same as your feeling of hungry?”
If you asked a neuroscientist this question (or one of the ones I proposed) they would say yes, because they all represent the same idea. Blue is a firing on mainly S cones which lead back to a certain region of the brain. Fear is a certain region of the amygdala responding to input. Hunger is the hypothalamus telling us our stomach is empty.
We can only talk about these things in such a way, as it is all we know they are.
