During the 18th and 19th centuries, procuring colors such as red, blue, and purple was a costly affair. Due to the limitations in dye technology, these hues became synonymous with aristocracy and the upper class.
In contrast, brown was the color of the working class, primarily because it could be dyed using inexpensive, earth-based materials. Not only was its production cheap, but it was also practical as it helped to hide the dirt on the clothes of laborers engaged in heavy work.
This cultural distinction became more pronounced during the Victorian Era. Agricultural laborers, coal miners, and railway workers became associated with brown attire. During these times, colors were indicators of one's social status. While the middle and upper classes gravitated towards brighter and more expensive colors, the lower class adopted brown as their color. This perception gradually permeated everyday life, literature, and the press.
