The official color of the Golden Gate Bridge is “International Orange.” 

It sounds like a flavor of soda that might give me mercury poisoning.

In the early 1800s, the Fugate family (better known as the “Blue” Fugates) lived in the hills of Kentucky… and many of them were blue.  Some of the family members possessed a hereditary genetic error called methemoglobinemia, which causes the blood to have reduced oxygen levels.  With lower oxygen levels, arterial blood that is typically red is instead brown.  In Caucasians, brown blood gives the skin a bluish hue.

I doubt the Fugates, though blue, even make it into the top 10 freakiest hereditary mutations to come out of the hills of Kentucky.

The “black box” on an airplane is really bright orange, so it can be found after a crash.

I am going to wear bright orange next time I fly.

I want them to find me, too.

In the United States, the AWWA and the NFPA recommend painting the top of fire hydrants different colors depending on the available flow of water.  I did not look up what those acronyms stand for, but I trust them.  Anyway, from strongest water flow to weakest, the colors go from light blue, green, orange, and red.  If you live in a neighborhood with a fire hydrant that has a light blue bonnet, congrats! You are a badass!
