Associations and expressions

In the English language, yellow has traditionally been associated with jaundice and cowardice. In American slang, a coward is said to be "yellowbellied" or "yellow."

Because it is similar to the gold color and precious metals such as gold or bronze, yellow is associated with coinage and bullion.

"Yellow journalism" is sensationalist journalism that distorts, exaggerates, or exploits news to maximize profit. The term came from Joseph Pulitzer's New York World and William Randolph Hearst's New York Journal American, who engaged in sensational reporting during the late 19th and early 20th century, most famously during the Spanish-American War. The term was derived from the color comic strip The Yellow Kid, which appeared in both papers.

They vary from single-celled flagellates to simple colonial and filamentous forms. Unlike other heterokonts, yellow-green algae's chloroplasts do not contain fucoxanthin, which is why they have a lighter color.
• The yellowhammer (Emberiza citrinella) is a passerine in the bunting family Emberizidae. It breeds across Europe and much of Asia. Most yellowhammers are resident, but some far northern birds migrate south in winter. It is common in all sorts of open areas with some scrub or trees. They are large with a thick seed-eater's bill. The males has a bright yellow head, yellow underparts, and a heavily streaked brown back. Females are much duller and more streaked below.

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 the rules of the road, yellow ("amber" in Britain) is a traffic light signal meaning "slow down," "caution," or "slow speed ahead." It is intermediate between green (go) and red (stop). In railway signaling, yellow is often the color for warning, slow down, such as with distant signals.
