Saw this rainbow on the way home from work this in Valencia, California
evening. It was really vivid. You can even see the secondary rainbow:

It has to do with the physics of how rainbows are created and the
refraction of the light. The inside will always be lighter than the
outside. You would need to search the web for an exact technical
explanation of why. Likewise, there is ALWAYS a secondary rainbow, but
it is often too faint to be seen. There are even tertiary and higher
order rainbows, but each one gets fainter and fainter, so they are never
seen.

Rainbows occur when sunlight and rain are both available the sky and
rain around the rainbow is always sunlit - you won't see the rainbow
otherwise. As the rainbow reflects some light (and so the sky appears
darker) but below the rainbow nothing is reflected making that part of
the sky brighter.
