A young girl named Wisp is brought to a grey, desolate land with the mission to bring colour to this world by locating the Sphere of Light. Along the way, she befriends a furry creature (called a sprite) named Twink and a magnificent horse named Starlite and finds a mysterious baby who turns out to be the key to her mission. With the help of her new friends, Wisp locates the legendary Colour Belt and rescues the seven Colour Kids, who had been trapped by the King of Shadows. Using the Colour Belt, Wisp and the Sphere of Light defeat the King of Shadows, liberate the sprites, and bring colour and beauty to the land, henceforth called Rainbow Land. Wisp is renamed Rainbow Brite in honour of her new role as leader of the Colour Kids, who are together in charge of all the colours in the universe.
Rainbow Brite and her friends (plus their Sprites!) were an iconic 1980's cartoon, who are still remembered and collected to this day.
