Brown in culture
Surveys in Europe and the United States showed that brown was the least popular color among respondents. It was the favorite color of only one percent of the respondents, among white and pink, and the least preferred color of twenty percent of the people, even less popular than pink, gray, and purple.

Brown uniforms
Brown has been a popular color for military uniforms since the late 18th century, largely because of its wide availability and poor visibility. When the Continental Army was formed at the outbreak of the American Revolution in 1775, the First Continental Congress declared that the official uniform color would be brown, but this was not popular with many militias whose officers were already wearing blue. In 1778, Congress asked George Washington to design a new uniform, and in 1779 Washington made the official color of all uniforms blue and buff.

In 1846 the Indian soldiers of the Corps of Guides in British India began wearing a yellowish tinge known as khaki, from the Urdu word for dusty color, from an earlier Persian word for earth. The paint made an excellent natural camouflage, and was adopted by the British Army for their Abyssian campaign in 1867-1868 and later in the Boer War. It was adopted by the United States Army during the Spanish-American War (1896) and later by the United States Navy and the United States Marine Corps.

In the 1920s, brown became the uniform color of the NSDAP in Germany. The Nazi paramilitary forces, the Sturmabteilung (SA), wore brown uniforms and were known as brown shirts. The color brown was used to put the Nazi votes on maps of electoral districts in Germany. When someone voted for the Nazis, it was said that they "voted brown". The National Headquarters of the Nazi Party, in Munich, was called the Brown House. The rise of the National Socialists to power in 1933 was known as the "Brown Revolution". In Adolf Hitler's house on Obersalzberg, the Berghof, he slept in a “bed that was usually covered by a brown quilt embroidered with a huge swastika. The swastika also appeared on Hitler's brown satin pajamas, embroidered in black on a red background on the pocket. He had a matching brown silk robe. “Brown was originally chosen as the party color, mostly for convenience; Large numbers of war-related brown uniforms from Germany ‘s former colonial forces in Africa were cheaply available in the 1920s. It also matched the images of workers and the military that the party wanted to convey. Until the 1930s, the party's brown uniforms were mass-produced by the German clothing company Hugo Boss (1885-1948). Boss became a member of the NSDAP in 1931 and was a licensed supplier to the SA, SS and the Hitler Youth. He was stripped of his voting rights and presidency of the company after World War II, but the company continued and still bears his name.

business
The color brown is intended to represent robustness when used in advertising. Pullman Brown is the color of the United Parcel Service (UPS) delivery company with their brands of brown trucks and uniforms; It was formerly the color of the Pullman Company's Pullman cars and was taken over by UPS because brown is easy to clean and because of the favorable associations of luxury that Pullman Brown has evoked. UPS has filed two trademarks on the brown color to prevent other shipping companies (and possibly other companies in general) from using the color if it causes “market confusion”. UPS refers to itself as "Brown" in its advertising.
