Variations in color perceived under different light, surrounding colors, or by the observer's sense of color. http://en.wikipedia.org/wiki/Metamerism_(color)

A marked change in the colour of an object with a change in the spectral composition of the light by which it is viewed.
NOTE:
Metamerism can be judged only with reference to the changes occurring in other objects in the fields of view as the illumination is changed.

A metamerism occurs when the color standard and the submit do not match under all lighting conditions. This means that a solid color fabric when viewed under two different lights in a commercial light box, will appear to cast two different colors. The correct technical definition for metamerism is a conditional match that is, two or more samples match for one observer under one light source, but not under a different light source for that same observer.
