Why Barns Are Red

 According to The Farmers’ Almanac and LiveScience, there is a very practical reason why farmers have traditionally painted their barns red, simple economics.

Most of America’s early farmers did not have money they could spend on paint to cover their barns. In fact, many of them could not even afford to paint their houses. Still, they needed to protect their barns from the elements so they experimented with various concoctions until they found one that worked.

Once it was developed and proven to work, word quickly spread that a proper mixture of skimmed milk, lime,
and ferrous oxide (rust) to kill fungi and as an extra sealant, and linseed oil would protect barn wood from rotting due to moisture. Luckily, those ingredients were in abundant supply on most farms of the day so they were available even to the poorest farmers. Incidentally, many houses in Sweden are red for the same reason.
