Is it possible that humans percieve colors differently?

I have been wondering about this for a while now. Is it possible that each person see colors differently? For example,  when I see the color orange,  is it possible that my wife sees it as what I would call purple? We can both point to it and say,  "That is orange!",  because to us,  it is our version of orange. But if I were able to see though her eyes,  with my current perception of colors,  it would appear to be purple. 

How could this be tested. Has it been tested? Any thoughts or comments?

Yes, what you describe is absolutely possible. What you are talking about the is "qualia" of a sensation, that is the internal representation. The same question could be the case for all sensations, pitch, roughness, taste... we could all experience different qualia from the same physical interaction.

With out current level of understanding, we have no way to test whether this is the case, nor even imagine how we COULD test if this was the case.
