Asked by Kap89 (49points) May 24th, 2009

I always think about this. Like growing up you are taught colors. But my blue could be his green which might be her purple… you know what i mean? i dont know, questions like this always make me wonder…

Yes we do. Our eye structures all have similar physiology and process light using the same method.

Therefore, barring any disorders such as colorblindness, we all see red as the same color.

Physically, every color has its wave length and human eye inteprets different wave lengths in such matter that we can distinguish them from one another. Nearly all human eyes use the same “interpretation” method and wave length is universal, so yes, we all see the same color.

I am colourblind so your colours are not the same to me ! .

What does it really mean to see? The only concrete way to define perception is as the set of changes in the brain resulting from the stimulation of the optic nerve, and it is obvious that there will be some discrepancy between individuals in the details of these changes. Those changes, in turn, evoke further changes, which we experience as instinctive emotional responses to the color; these cannot be divorced from the earlier changes, with the first being classified as “vision” and their successors as “interpretation”. All of these must be considered part of the perception of color, and they must necessarily be different for each person. At the same time, however, the similarities in physiology referenced by others above mean that the differences will generally be slight.

This is a guess, but I would say there is a RANGE of hues people might see when they look at a specific color (let’s say there are 1 of 10 possible shades of red one might see when he looks at red) and a certain percentage of people see “red 1”, a certain percentage see “red 2”, etc.. Plus I wouldn’t be surprised if the color red you see changes with your age.

So it would be with hearing, smelling, tasting and even pain thresholds. Notice how babies and children tend to find hypodermic needles more painful then adults??

I wonder how we’d ever prove this one way or another?
