The Color Belt is magical artifact and arguably the most powerful force in Rainbow Land, though the extent of it's power is largely unspecified.
Depiction in the original seriesEdit
In "Beginning of Rainbowland - Part 2", it is revealed that the Color Belt rested within Baby Bright. More to the point, Baby Brite was the Color Belt. The belt can presumably only work if wielded by one who possesses a pure and honest heart. It has been wielded on rare occasions by Rainbow Brite, particularly during moments of great danger as a last resort to restore color and peace. However, the effects of it's use are generally non-lethal, usually a form of banishment or imprisonment. Rainbow can use it for other various feats as well, including enabling Starlite to fly by creating a bridge for him to travel on.
