The absorption of light gives a pigment its colour and its reason for being, but it also creates excited states, that is, new molecules with an energy excess that can be dissipated through degradation pathways.

Control of Colour Change in Amphibians
Nature, 1960THE adaptation of colour in anurans to the background is controlled by hormones. Direct innervation of the melanophores is of little or no importance in controlling the degree of dispersion of the melanin-containing granules within the melanophores1.

Colour and colour change in the grasshopper, Kosciuscola tristis
Journal of Insect Physiology, 1975Abstract The males of the small grasshopper (Kosciuscola tristis), with a restricted range above 1830 m in the Australian Alps, exhibit a remarkable colour change. They are dark, almost black, when cold and change to a bright sky blue colour within minutes of exposure to warmth.

A System for Finding Changes in Colour
Procedings of the Alvey Vision Conference 1987, 1987We acquire a great deal of information about the world about us by perceiving the colour of objects. We can manage without colour, but certain tasks can become rather difficult telling ripe from unripe fruits, or finding green tennis balls lost in grass, for example. Yet colour information is seldom used by the machine vision community, although, given

Serotonin and Change of Colour in Frogs
Nature, 1959IT is well known that intermedin, a secretion of the pituitary, is responsible for the dispersion of the pigment in the melanocytes of frogs. The identity of the secretion has remained a mystery; indeed, there are few compounds capable of causing the darkening of hypophysectomized frogs.

Changing cable identification colours
First IEE International Conference on Building Electrical Technology (BETNET), 2004As from 1st April 2004, electrical installations in the U.K. may use, for fixed wirings, the new harmonised cable core colours or the pre-existing colours but not both. However, BS7671:2001 (incorporating Amendments 1 & 2) requires any work commencing on site after 31 March 2006 should not use the old colours but to comply with the new colours in full.

Conditions of the Colour Change of Prodigiosin
Nature, 1967THERE have been several reports that prodigiosin, the pigment produced by Serratia marcescens, is red in acid solution with an absorption maximum at 535–540 mμ but is yellow–orange in alkaline solution with an absorption maximum at 470 mμ. (refs. 1 and 2).
