Now this was a challenge. Could not quite decide what to submit but settled on a series of photos of earthquake anchor bolts in brick walls. The color of the brick or stucco varies from red to orange or even red-orange. Depends upon your eye, lighting conditions and the settings on your monitor, I suppose.
Earthquake anchor bolts are quite common on older buildings with brick facades. They are supposed to keep the walls from falling down in an earthquake…or so the story goes
IN ANY EVENT, THIS IS THE BEST I CAN DO FOR THIS CHALLENGE! 🙂
