What does uncoloured mean?
Uncoloured means without colour, in either a literal or figurative sense. Literally, it describes an object, surface, material, or image that has no coloration: clear uncoloured glass, for example, transmits light without a visible tint. Figuratively, it can describe an opinion, account, or judgment that is impartial and not influenced by bias, preference, or emotional pressure. The word is especially associated with British English, where colour retains its -our spelling; American English generally uses uncolored. Although colourless is more familiar in many contexts, uncoloured can be useful when the absence of colour itself is the point or when its broader sense of neutrality needs to be emphasized. In figurative use, it should not be taken to mean ignorant, inexperienced, or indifferent—only that the subject is presented without prejudice. The transparent pairing of the prefix un- with colour also makes the word especially accessible to learners.
