Little is documented about where this particular rainbow clip first appeared, and it is best understood as a short user-shared sound rather than a line from a known film or show. Its appeal comes from the word itself, which is widely associated with colour, optimism and surprise, making it easy to reuse across very different videos. Creators have picked it up for quick edits, memes and reaction-style clips, where a single familiar word can carry a joke or a mood change without needing any explanation.
关于此声音
A short sound effect clip featuring the spoken word rainbow, used by creators for colourful reveals, jokes and playful moments in videos and memes.
This is a brief, one-second clip built around a single spoken word, rainbow, delivered clearly and with a bright, upbeat lift that makes it instantly recognisable even out of context. The voice sits front and centre with no music or background noise to distract from it, so the word lands cleanly and leaves a cheerful, slightly whimsical impression. That simplicity is what gives it its punch in editing: it can brighten a dull moment, underline a colourful visual, or act as a tiny punchline without taking over the scene around it.
