'monochrome' originates from Greek, specifically the word 'monokhrōmos,' where 'mono-' meant 'single' and 'khrōma' meant 'color.'

'monokhrōmos' transformed into the French word 'monochrome,' and eventually became the modern English word 'monochrome' through Middle English.

Initially, it meant 'single color,' and this meaning has largely remained the same in modern usage.
