Did you know there really is no such thing as Blue Food? Even though Steak-in-Shake restaurant would have you believe otherwise. George Carlin once said that if you find a really true blue food you will have found the key to eternal life. Even blueberries are not really blue. Ever make a blueberry smoothie? It's purple.
Here's another thing to ponder? Why is artificially flavored raspberry "food" colored blue? Ever get a Dairy Queen rasberry Mr. Misty or eat a rasberry otterpop when you were a kid? YIKES!
Wait....what about blue cheese?
