In ancient times, the world was colorful but the gods made it grey to punish selfish humans. Many years later, after humans became more respectful, a wise man asked the god Elios for forgiveness. Elios took pity and sent the sacred bird Arcos to return color to the world by dropping blue, green, and yellow feathers in the sea, forest, and sky, then other colors everywhere else. As a reminder of Arcos' good deed, Elios placed a rainbow in the sky.
