Reply to comment by sbvp in The sky is a different colour on either side of this rainbow by samyall
It actually is brighter. The dark region beyond the rainbow is called Alexander's Band. Good explainer of the physics

Rainbows are not simple! It says that white sunlight is reflected back from inside/under the rainbow, but not above/outside the rainbow (until we get to the colour-inverted secondary rainbow).
[Edit: deleted repeated info about Alexander's Band]
