I see that you already got a decent answer. But I have a related one:
Is it only me or does the sky beneath a rainbow also appear lighter
to others than the sky above a rainbow (or wait, was it the other way
around?)? But anyway, for my eye there is definitely a jump in
brightness of the background sky (normally rain clouds) from beneath
to above the rainbow. Any explanation for this?
