It's not something to whine about. Bringing Kentucky into it is just random. It's not like we're stealing anything or copying anyone. If you're not secure enough in your fanhood to, Heaven forbid, have the same color as another team, maybe it's time to chill a bit. There are all sorts of shades of royal blue. Duke's is as well. OH NO, DUKE!!! CAN'T DO THAT OH NO!
And actually, I have lived in Kentucky. But if I have a blue shirt on that says BYU, it doesn't make me a UK supporter. You're getting way too technical and being a baby about a color and the "meaning" of it is just sad.
