Accident with red blood to bring blue to the world.

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.
