Wooden buildings often aren’t arbitrarily red.
Falu red (pronounced “FAH-loo”, in Swedish it’s Falu rödfärg) is the name of a Swedish, deep red paint well known for its use on wooden cottages and barns for preservation. The paint originated from the copper mine at Falun in Dalarna, Sweden and consists of water, rye flour, linseed oil and tailings from the copper mines of Falun which contain silicates iron oxides, copper compounds and zinc. Falu red is still widely used in the Swedish countryside.
