Yellow color - Symbolism

• Yellow was the symbol for the Emperor of China and of the Chinese monarchy. It was also the color of the New Party in the Republic of China.
• Pencils are painted yellow because of this association with China, where the best graphite is found. Only pencils with Chinese graphite used to be painted yellow.
• Yellow also symbolises royalty in many other cultures, like much of South East Asia. In China, commoners were not allowed to wear yellow until modern times.
• In the United States in the 20th century, immigrants from China and other East Asian nations were derogatively referred to as a "Yellow peril", which probably referred to skin color.
• Yellow, in international political organizations, is the color for liberalists.
• In some countries, taxicabs are commonly yellow. This practice apparently began in New York City, where taxi owner Harry N. Allen painted his taxis yellow after learning that yellow is the color most easily seen at a distance.
• In Canada and the United States, school buses are almost uniformly painted a yellow color (often referred to as "school bus yellow") for purposes of visibility and safety, and British bus operators such as FirstGroup are attempting to introduce the concept there. "Caterpillar yellow" and "high-visibility yellow" are used for highway construction equipment.
• In Association football (soccer), the referee shows a yellow card to indicate that a player has been officially cautioned.
• In auto racing, a yellow flag signals caution. Cars are not allowed to pass one another under a yellow flag.
• In cycle racing, the yellow jersey - or maillot jaune - is awarded to the leader in a stage race. The tradition was begun in the Tour de France where the sponsoring L'Auto newspaper (later L'Équipe) was printed on distinctive yellow newsprint.
