Barns would just look weird if they were any other color than red.
New England settlers didn't have money to paint their barns so they mixed skimmed milk, lime, and red iron oxide to make a red plastic-like coating to protect their barn's wood.
According to a Business Insider video, "Red absorbed more of the sun's rays than plain wood and was the cheapest at the time. The coating protected the wood and kept it warmer in the winter." Once manufacturers started making paint with chemical pigments red was still the cheapest, so farmers just stuck with the color red.
