Iridescence (Eastercon 2026)
Birmingham, United Kingdom · 3–6 Apr 2026 · T2 Strong
Iridescence (also known as goniochromism) is the phenomenon of certain surfaces that appear gradually to change colour as the angle of view or the angle of illumination changes. Iridescence is caused by wave interference of light in microstructures or thin films. Examples of iridescence include soap bubbles, feathers, butterfly wings and seashell nacre, and the mineraloid opal.
