What does colourize mean?
To colourize something is to add colour to it, most commonly referring to the digital process of converting black-and-white photographs or films into full colour. The word is the British-spelling counterpart of the American "colorize", and both are built on "colour" plus the verb-forming suffix "-ize". Colourization became widely known — and controversial — in the 1980s, when studios began artificially adding colour to classic black-and-white films, prompting objections from directors and film historians who felt the originals were being compromised. Today the word appears frequently in discussions of digitally restored archives, AI-assisted photo enhancement, and historical imagery brought into colour for modern audiences. Beyond imaging technology, it can occasionally be used figuratively to mean making an account or description more vivid, though this sense is far less common. Writers should choose the spelling that matches their regional convention: "colourize" for British English, "colorize" for American English.

Etymology of colourize
Colourize combines "colour", which entered English from Old French "colour" and ultimately from Latin "color", with the suffix "-ize", borrowed from Greek via Latin and French, which forms verbs meaning "to make or treat as". The compound arose in modern English as photographic and film technologies created a need for a term describing the addition of colour to monochrome images. Its American variant "colorize" reflects the simplified spelling of "color" introduced by Noah Webster. Related words sharing the same root include "colourful" and "discolour".
