Iridescence is a spectacular colour effect found in natural and artificial materials and in atmospheric effects on light.

It is defined by the reflectance of multiple colours from the same material (which may be solid, liquid or gas) and a change in the hue and intensity of the reflected light with a change in the angle of viewing or of illumination. It is caused by multiple physical phenomena, and its consequences in biological, psychological and engineering contexts remains to be fully understood.

On Wednesday 3rd February we hosted four speakers with radically different perspectives on the subject of Iridescence.
