Best Answer

The Rainbow Badge from Celadon Gym is the fourth badge on a Trainer's quest toward the Indigo League.

In the games, it enables the use of Strength outside of battle and forces all Pokémon up to Level 50 to obey the Trainer.

Erika has the sole authority to hand out the Rainbow Badge.

It is shaped like a flower, showing grass. Its petals are rainbow colored, hence its name.
