In the late 1950s, one of the favorite colors for cars, especially Ford Thunderbirds, was robin's egg blue. If I am not mistaken, I believe the car Suzanne Somers drove in American Graffiti was one.
Anyway, for some reason, the whole robin's egg blue thing made me think about how when I would ask my mother a question, especially as it regarded color, if she didn't know the answer, she would say, "Sky-blue pink," when she didn't know the answer. And if she was particularly befuddled or frustrated or just annoyed, she would embellish it with, "sky-blue pink with yellow polka dots." Or maybe "...with green roses." In other words, I don't know, just stop.
So imagine my surprise when I googled the phrase and found out it was a real thing! Yep, goes way back. It was popular in London, but apparently originated here in the states. Who knew? You can read all about it here: Sky-Blue Pink Etymology. This of course is just one of the expressions I heard growing up, usually from my mother or my grandmother. And sometimes they come back to me while watching Jeopardy. And to think they actually were real things!
I could write a book.
In the meantime, there is a short animated film starring the Pink Panther called Sky Blue Pink!
Enjoy! Don't say I don't inform, educate and entertain. Where else would you get all this in one blog?
