Why Are Barns Painted Red?
Historically, farmers treated barn exteriors to protect them.
Some speculate that barns’ red coloring was once derived from animal blood.
Some claim that wealthy farmers would add the blood of their recent slaughter to the oil mix. There isn’t much historical data on the topic, so no one can say for sure whether this is true.
A more likely answer is iron oxide.
Red barn paint later caught on because of its low price.
Today, barns are painted red out of tradition.
This is a centuries-old custom that isn’t likely to fade any time soon, and we hope it never does.
