This morning my girlfriend was telling me about her new shampoo, that comes without additives and sulfates and all that jazz.
GF: It's called "no poo" shampoo
Me: Sounds like a bit of a sham to me
She didn't get it.
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.
