A device or substance that changes color when subjected to rotation or gyroscopic forces; used in certain scientific instruments.
Compound from 'gyro-' (rotating) and '-chrome' (Greek chroma meaning 'color'). This technical term emerged in 20th-century physics as scientists explored rotating systems.
Gyrochromes demonstrate that spinning forces can literally change how materials interact with light—it's like the whole universe shifts color when things spin fast enough!
