True Blue Puns

That's what Xi said.

It took an accident with red blood to bring blue to the world.

A pigment maker named Diesbach was trying to create a popular red out of cochineal, an insect still used for red dye in everything from lipstick to ketchup.

He added iron sulfate mixed with potash which we later discovered has a useful element now called potassium.

Anyway, the potash he used was contaminated with animal blood, which contains iron, and rather than creating red, he accidentally invented an affordable, long-lasting true blue.

When it came to making red pigment... he really BLUE it.

Just got back from shopping for new work clothes with my girlfriend. She picked out two button-down shirts for me to consider. The first was a blue-green color. I told her it wouldn't work because it doesn't match most of my ties.

The second shirt was solid gray. "You could wear a lot of your ties with this color," she said.

"True," I said. "But wearing more than one would look kind of silly."
