Seina Compact Outdoor Folding Utility Wagon, Black

Black is a color that results from the absence or complete absorption of visible light. It is an achromatic color, without hue, like white and grey. It is often used symbolically or figuratively to represent darkness. Black and white have often been used to describe opposites such as good and evil, the Dark Ages versus the Age of Enlightenment, and night versus day. Since the Middle Ages, black has been the symbolic color of solemnity and authority, and for this reason it is still commonly worn by judges and magistrates.

Black was one of the first colors used by artists in Neolithic cave paintings. It was used in ancient Egypt and Greece as the color of the underworld. In the Roman Empire, it became the color of mourning, and over the centuries it was frequently associated with death, evil, witches, and magic. In the 14th century, it was worn by royalty, clergy, judges, and government officials in much of Europe. It became the color worn by English romantic poets, businessmen and statesmen in the 19th century, and a high fashion color in the 20th century. According to surveys in Europe and North America, it is the color most commonly associated with mourning, the end, secrets, magic, force, violence, fear, evil, and elegance.

Black is the most common ink color used for printing books, newspapers and documents, as it provides the highest contrast with white paper and thus is the easiest color to read. Similarly, black text on a white screen is the most common format used on computer screens. As of September 2019, the darkest material is made by MIT engineers from vertically aligned carbon nanotubes.

In economics, utility is a measure of a certain person's satisfaction from a certain state of the world. Over time, the term has been used with at least two meanings.

• In a normative context, utility refers to a goal or objective that we wish to maximize, i.e., an objective function. This kind of utility bears a closer resemblance to the original utilitarian concept, developed by moral philosophers such as Jeremy Bentham and John Stuart Mill.
• In a descriptive context, the term refers to an apparent objective function; such a function is revealed by a person's behavior, and specifically by their preferences over lotteries.

The relationship between these two kinds of utility functions has been a source of controversy among both economists and ethicists, with most maintaining that the two are distinct but generally related.

A wagon (or waggon in British English) is a heavy four-wheeled vehicle pulled by draft animals or on occasion by humans, used for transporting goods, commodities, agricultural materials, supplies and sometimes people.

Wagons are immediately distinguished from carts (which have two wheels) and from lighter four-wheeled vehicles primarily for carrying people, such as carriages. Animals such as horses, mules, or oxen usually pull wagons. One animal or several, often in pairs or teams may pull wagons. However, there are examples of human-propelled wagons, such as mining corfs.

A wagon was formerly called a wain and one who builds or repairs wagons is a wainwright. More specifically, a wain is a type of horse- or oxen-drawn, load-carrying vehicle, used for agricultural purposes rather than transporting people. A wagon or cart, usually four-wheeled; for example, a haywain, normally has four wheels, but the term has now acquired slightly poetical connotations, so is not always used with technical correctness. However, a two-wheeled "haywain" would be a hay cart, as opposed to a carriage. Wain is also an archaic term for a chariot. Wain can also be a verb, to carry or deliver, and has other meanings.

Contemporary or modern animal-drawn wagons may be of metal instead of wood and have regular wheels with rubber tires instead of traditional wagon wheels.

A person who drives wagons is called a "wagoner", a "teamster", a "bullocky" (Australia), a "muleteer", or simply a "driver".

Wagons have served numerous purposes, with numerous corresponding designs. As with motorized vehicles, some are designed to serve as many functions as possible, while others are highly specialized.
