I recommend the answer by Dr Arvind Singh , but with aging the capacity of eye to distinguish the color also decreases.

yes, it depends to human and environmental factors

Probably 10 million different colors .

Note: The hunan eye does not distinguish any color! The retina is only capable the produce differeciated neuro electrical patterns that can be perceived by our brain as a sensation that we call color. And the sensation of a color it self depends on the importance of the perceived visual stimulus for our sourviving in a specific habitat.

When viewed in full size, this image contains about 16 millionpixels, each corresponding to a different color on the full set of RGB colors. The human eye can distinguish about 10 milliondifferent colors.
