What are the causes of color change in organic substances?

Question asked by: aegeanpua

Asked on: 17 Oct 2008

A change of pH can cause colour changes; also response to threats in the environment; secretion of chemicals from glands in the skins of animals and all sorts of other reasons besides.

Ultimately it is due to a change in the chemistry resulting in different wavelengths of visible light being absorbed and reflected by the constituent atoms; depends if you want an answer from chemistry, physics or biology!
