Search For Love #1 (1950) has a little piece on wedding superstitions, including this:
I've never heard this "ditty"...then again, I've never been a prospective bride worrying about what color to wear at my wedding.
Also, I'm still showing my ignorance here...but are there people who really get married in red? Green?
The ditty does a good job of going through Geoff Johns' "emotional spectrum" of Color Corps, though. "Married in blue, turn into a shrew?" "Married in indigo, you will get vertigo?" "Married in orange...?" That's why nothing rhymes with orange--an Orange Lantern would never get married, because then they'd have to share!!
Another wedding superstition:
Of course, if the evil spirit were any good at all, if it got confused it would just hex everyone in the party...
