Light is an electromagnetic vibration. Like waves in the ocean. It is characterized by its wavelength. If the wave crests are densely packed and close together the wavelength is short and the color is violet (then ultraviolet), if the wave crests are far away the wavelength is long and the color is red (then infrared). Anything in between can be blue, green, yellow and many shades of it.
The colour of light is dictated by its wavelength. It spans the colour of the rainbow. If you have an equal proportion of all colours, the light is white, like our sun.

Light from many sources, such as the sun, appears white. When white light passes through a prism, however, it separates into a spectrum of varied colours. The prism bends, or refracts, light of different colours at different angles. Red light bends the least and violet light bends the most.

If you are talking about visible light the color changes depending upon the wavelength. It also depends on the object that it is interacting with. If the wave lengths are shorter than the light is Violet and if they are longer than they are more red.

light has no colour.
our brains interpret colour based of the frequency of the light we absorb on the backs of the retinas...
The fact is what you mights see as red might be what I see as green. think about it. if you grow up being told that object there is Green, then you know that it is green. case in point. if a person who has been totaly blind all there life ( ie only sees black {no light enters the retina} and suddenly sees they would be unable to interpret the colours and wouldn't be able to discuss them with someone else until they have been told what is what by someone else.

Light is not a single color. Light is an energy where at different wavelengths your eye sees different colors.

Light is the color as shown through the color spectrum. The absence of all color is black. The inclusion of all color makes white.
