|This is part of the Sky Pretty Cure Series!|
The Rainbow Pact (レインボーパクト Reinbō Pakuto?) is a mythical item that appears in the Sky Pretty Cure Series. The Rainbow Pact makes it's debut in the first season. The Rainbow Pact is used to collect the legendary Rainbow Tears and turn their power into the legendary crystals once all Tears are collected.
In Sky Pretty Cure ~Rainbow Star~, the Rainbow Pact appears along with Purple and Pink, when they arrive at earth. Together with the powers of those two, the Rainbow Pact grants Rubellit and Amethyst the power to transform into Pretty Cure, by shouting "Double Rainbow Painting!".
In the second season, the Rainbow Pact is used by Rubellit and Amethyst to transform into Pretty Cure. The Heaven Crystals still exist in the Pact and the Cures can use them. It also creates the Color Palette the ultimate upgrade weapon for Pretty Cure.
