Answer 1

Color in light is defined by wave length. When you see the color "purple", you're seeing a specific wave length of light, and the wave length is exactly the same for me.

The real question is whether your brain interprets the signal in the same way. Unless you're color blind, the answer is yes, we sense the same color.

Answer 2

Colors of objects are the color that they reflect.
A red object reflects red light and absorbs the rest.
White objects reflect all wavelengths.
Black objects absorb all wavelengths.
The concept of color is scientific. Exact wavelength and frequencies effect the retina a certain way.
Some people have color blindness and are unable to see some or all colors.
The exact color that you see may seem different to me.Many artists are able to mix colors to exactly match a given color, even if they might call it a different name.

Answer 3

Since we're basically a product of the same genetic material, I suspect that we pecieve colors the same.
