Iridescence
noun /ˌɪr.ɪˈdes.əns/ — A shifting, rainbow-like shimmer that changes with the angle of light
Definition
The quality of showing luminous colours that change and shift when seen from different angles — like the inside of a shell, a dragonfly's wing, or a soap bubble. Colour that is not fixed but alive.
Beyond the definition
The feeling of something that cannot quite be caught. Iridescence is the visual equivalent of elusiveness — beauty that changes the moment you move toward it, that refuses to be pinned down to a single colour.
Origin & history
From Latin 'iris' (rainbow) + '-escence' (becoming). The goddess Iris was the rainbow — the divine messenger who moved between earth and sky. Iridescence is what she left behind: colour that travels.
