Non-Standard Roadsign Colors

It has been too long since I have posted any road geek photos, so let's remedy that right now. This is a picture of a 'YIELD' sign I saw in a Phoenix parking lot. I didn't Photoshop it, and yes, it is really blue. Looks weird, doesn't it?

Looks Like The Rolling Stones Logo

Michael Shermer, publisher of Skeptic Magazine, says humans are pattern seeking animals. This is why we see shapes of familiar things in the clouds and stars; and why people see the Virgin Mary in a grilled cheese sandwich.

I am not immune to this human trait. I noticed this hole punched in the tile of the cafeteria floor at work today. To me, it looks like the logo of the Rolling Stones, you know it...the open mouth with a tongue sticking out. What do you think?
