Iridescence and holography are two techniques used in security printing to display colour shifting phenomena that depend on the angle of viewing or illumination of a surface. Colour shifting phenomena also occur naturally in nature, such as the iridescent shimmer of a butterfly’s wings due to the precise structure and arrangement of the microscopic scales on its wings.
