If when you think of a farm you visualize a red building with white corners, it’s the Swedes’ fault.

5040-Y80R. That is the approximate designation according to the Natural Color System chart for color ‘red falu‘. It is a registered trademark and It goes beyond being a simple color: implies that a very specific pigment comes into play in its production that gives it that reddish tone and has transcended to the point of being part of the identity of an entire country thanks to its properties. That country is Sweden, and it all started as a waste product from a copper mine. By-product. Dalarna is a region located in the heart of Sweden, and it is home to the Falun Great Copper Mountain. The Vikings They were already exploiting this mine in 850, but the history of color dates back to the 16th century. It was then that they discovered that one of the mining byproducts could be turned into a useful pigment. Leaf From the production of copper they obtained what they called Falu rödfärgor “red mulch,” and was basically a unique mixture of over 20 different minerals. The reddish color was thanks to iron oxide, silica, zinc and copper itself. They started to mix it up with water, but also with other elements such as oils, tar or rye flour, and they discovered that they could obtain a paint with very interesting properties. better than paint. This red mulch mixed with the appropriate ingredients not only gave color to the wood, primary raw material in Sweden for both ships and infrastructure, but also acted especially well as a material protector. It was like an insulating layer, a shield that protected against the elementsprolonging its useful life, making repairs less frequent and, in addition, it was cheaper than importing wood treatments from other countries. The industry soon exploded. HE esteem that, by mid-1760, production was about 25 tons, but by 1930, that annual production exceeded 2,000 tons. Status. Now, it wasn’t cheap. Everyone wanted to paint their house that copper red color, but it turns out that it was a luxury reserved for the highest classes. When the pigment was discovered, and perhaps motivated only by its color, King John III ordered paint the ceilings of his palace with ‘falu red’, imitating the copper of the ceilings of other European palaces. Since then, those with the most power who could get hold of the pigment began to paint their houses. However, as production began to scale and gain traction, the product became cheaper and more people were able to access it, painting, if not all of their houses, the façade that faced the roads (which was what everyone passing by could see). Swedish edges of the 19th century contributed to popularize the image of the red houses of Sweden, immortalizing the idea of ​​rural life in red houses with white corners. One of Carl Larsson’s works The color of a nation. The color 5040-Y80R became the symbol of Sweden to the point that migrants who sought better luck in North America after the dissolution of the norwegian swedish union In 1905 they began to build their farms using this color. The image that many of us have of the red farm was created there. And it became so important to Swedish popular culture that there is a saying that symbolizes that simple life and harmonious in contact with the earth: den röda stugan och potatislandet (the red house and the potato garden). Today, the ‘Falu rödfärg’ is not as vital as it was years ago if we talk about production. The same has descended a lot because there is greater competition and synthetic products for paint the facadesbut it is still an example of “banal nationalism”, a symbol that exists without the need for flags and anthems, since its mere presence evokes belonging.
