A little girl named Wisp is brought to a colourless land. To bring colour back to the land she must find the Sphere of Light.
Along the way she befriends a sprite named Twink, a white horse named Starlite and a mysterious little baby.
Wisp goes onto to find the Colour Belt and rescues the 7 Colour Kids.
After using the belt to defeat the King of Shadows, Wisp is renamed Rainbow Brite. She, the Colour Kids and Sprites live in Rainbow Land and are in charge of all the colours in the universe.
Rainbow Brite ran for 13 episodes between 1984-1986 and also spun off into a movie that differed slightly from the cartoon. A short lived reboot took place last year.
