Why is there no blue food?

[Food Network Fan]

George Carlin: Why is there no blue food? I can't find blue food - I can't find the flavor of blue! I mean, green is lime; yellow is lemon; orange is orange; red is cherry; what's blue? There's no blue! Oh, they say, "Blueberries!" Uh-uh; blue on the vine, purple on the plate. There's no blue food! Where is the blue food? We want the blue food! Probably instores immortality! They're keeping it from us!

There's blue potatoes and blue corn. Both have a deep blue color.

And, there's blue crabs.

I thought they were blue.

They look kind of blue when they are growing but when you eat them they are purple.

[Bentley Green]

They also look blue when you make or eat blueberry pie. At least the sauce they're in looks blue.

How about bluefish?

I am still going with purple. You and my husband must have the same color labeling.
