Has anyone gotten a red-colored chip from the Chipotle chips?!

I got dinner from there today, and one of the chip's had a red coating on it. It seemed like some pepper or something, but none of the other chips were like that. I ate it without thinking much, and it tasted like chili pepper, but it hit me afterwards that it was strange none of the other chips were colored that way. I'm totally paranoid about blood disease, and for some reason, the thought keeps coming into my head that it might've been blood. It tasted nothing like blood, but that thought keeps coming into my head.

Has anyone ever seen a red chip like that? If not, I mean, how likely is it that it was blood on it?

Thanks for answering. Sorry this sounds so weird.
