Opalescent
adjective /ˌəʊ.pəlˈes.ənt/ — Showing shifting, milky colours like an opal
Definition
Showing a shimmering, shifting play of colours — reflecting light in a way that seems to change and move, like the surface of an opal.
Beyond the definition
The quality of beauty that refuses to settle into one colour. Opalescent things keep the eye moving, keep producing new versions of themselves.
Origin & history
From 'opal' + '-escent' (becoming, displaying). Opals were prized in ancient Rome as the most beautiful of gems precisely because they contained all colours at once.
