White light contains all the colors of the rainbow. We usually list these as red, orange, yellow, green, blue, indigo, and violet, but there really are all the colors in between, all wavelengths. That might include red orange, blue green, yellow green, and so on.

The human eye is capable of distinguishing over 100,000 different shades of colour, and all these and more are present in the spectrun of white light. However, when light (from a star, for example) is broken down in a spetroscopic analyser, sometimes there are dark areas in the spectrum, where some colour frequencies are not present. These are called absorption bands, where particular wavelengths of light have been absorbed by certain elements (hydrogen, for example). By analysing those bands, scientists can determine the chemical makeup of stars.

Zero... White light is white. However, when white light bends due to defraction and scattering, it reflects light in many different colours that is visible in the electro magnetic spectrum. differant particles scatter light in different ways and the intensity of the coloured light that is reflected back to the human eye is the result of the object not being able to absorb that spesific colour.
