Description
An optical effect in which a material shows two different colors under different lighting conditions. For example, under plane Polarized light, Calcite crystals will change colors from blue to pink when viewed at different angles. Some materials, such as Alexandrite, Cobalt yellow, and Chlorophyll solutions, exhibit different colors when viewed in reflected versus transmitted light. A dichroic mirror is designed to reflect some wavelengths while transmitting others.
See also anisotropic, and Birefringence.
