Our eyes are sensitive to light which lies in a very small region of the electromagnetic spectrum labeled "visible light". This "visible light" corresponds to a wavelength range of 400 - 700 nanometers (nm) and a color range of violet through red. The human eye is not capable of "seeing" radiation with wavelengths outside the visible spectrum. The visible colors from shortest to longest wavelength are: violet, blue, green, yellow, orange, and red. Ultraviolet radiation has a shorter wavelength than the visible violet light. Infrared radiation has a longer wavelength than visible red light. The white light is a mixture of the colors of the visible spectrum. Black is a total absence of light.

Actually the concentration of the cone photoreceptors in relation to one another changes the appearance of the "color" you see. So red likely does look slightly different to most people.

This link simplifies things a bit. Essentially if one of the cones is in lower concentration it shifts the average view of what you see. However, because we have named these colors our whole lives (ie. Apples are red) we have each learned what colors are attributed to our personal shades.
