maybe that Rolling Stones song is not that stupid: it's about a girl who brings colors, meaning she brings joy, she is.. "sunny", bright.
Like the rainbow that clears and colors the air after the rain...
and so when he sees her, he feels that she's similar to the rainbow

That part isn't bad, it is the part where they say "she combs her hair"

That just seems to me to be a bad line stuck in there just for rhyming. I don't know, maybe i am being harsh, but it helps to hear the song to get the full silliness of it
