K&B purple

Since I'm a pharmacist in New Orleans, I thought it would be nostalgic and charming to have a K&B coffee mug. K&B was an iconic pharmacy chain in New Orleans, and much-loved until they sold out to Rite Aid. Their symbol is a K and B in a purple oval; that signature color is known in New Orleans as "K&B purple".

Except my mug isn't. It's pink.
Huge fail. A K&B mug that's the wrong color. I've already been mocked for it.
As one of my friends said, perhaps the color faded on the trip from China?
