Buff (colour)

Buff is the pale yellow-brown colour of the un-dyed leather of several animals.

As an RYB quaternary colour, it is the darker colour produced by an equal mix of the tertiary colours citron and russet.

Etymology

The first recorded use of the word "buff" to describe a colour was in the London Gazette of 1686, describing a uniform to be "...a Red Coat with a Buff-colour'd lining". It referred to the colour of un-dyed buffalo leather, such as soldiers wore as some protection: an eye-witness to the death in the Battle of Edgehill (1642) of Sir Edmund Verney noted "he would neither put on armor or buff coat the day of the battle". Such buff leather was suitable for buffing or serving as a buffer between polished objects. It is not clear which bovine "buffalo" referred to, but it may not have been any of the animals called "buffalo" today.

Derived terms

The word "buff" meaning "enthusiast" or "expert" (US English) derives from the colour "buff", specifically from the buff-coloured uniform facings of 19th-century New York City volunteer firemen, who inspired partisan followers among particularly keen fire-watchers.

Greeks (finance)

In mathematical finance, the Greeks are the quantities representing the sensitivity of the price of derivatives such as options to a change in underlying parameters on which the value of an instrument or portfolio of financial instruments is dependent. The name is used because the most common of these sensitivities are denoted by Greek letters (as are some other finance measures). Collectively these have also been called the risk sensitivities,risk measures or hedge parameters.

Use of the Greeks

The Greeks are vital tools in risk management. Each Greek measures the sensitivity of the value of a portfolio to a small change in a given underlying parameter, so that component risks may be treated in isolation, and the portfolio rebalanced accordingly to achieve a desired exposure; see for example delta hedging.

The Greeks in the Black–Scholes model are relatively easy to calculate, a desirable property of financial models, and are very useful for derivatives traders, especially those who seek to hedge their portfolios from adverse changes in market conditions. For this reason, those Greeks which are particularly useful for hedging—such as delta, theta, and vega—are well-defined for measuring changes in Price, Time and Volatility. Although rho is a primary input into the Black–Scholes model, the overall impact on the value of an option corresponding to changes in the risk-free interest rate is generally insignificant and therefore higher-order derivatives involving the risk-free interest rate are not common.

Color (band)

Color (stylized as COLOR) was a Japanese punk band formed in 1985 by Dynamite Tommy, who founded the Free-Will record label a year later. They are considered to be important to the formation of visual kei. Their debut album Gekitotsu was named one of the top albums from 1989-1998 in a 2004 issue of the music magazine Band Yarouze.

History

Color released their debut album Gekitotsu, in January 1988. After releasing their second album Fools! Get Lucky!!, they signed to Crown Records and released their only major studio album a couple months later, Ask the Angels. It is said that the label made the band rewrite the album's lyrics, which were originally in English, in Japanese to be more accessible by the mainstream. It seemed to have worked, as Ask the Angels reached number 16 on the Oricon chart and their popularity increased. However, in January 1990 at a concert on the album's tour, in their hometown of Osaka, a fan was accidentally stomped to death. The band decided to lay low and avoid media, they ended up losing their contract with Crown. During this hiatus, Tommy formed Sister's No Future with Ken-chan (Kamaitachi), while Marry started Goatcore with You Adachi (Dead End).

Status effect

In role-playing games, a status effect is a temporary modification to a game character’s original set of stats that usually comes into play when special powers and abilities (such as spells) are used, often during combat. It appears in numerous computer and video games of many genres, most commonly in role-playing video games. The term status effect can be applied both to changes that provide a character an advantage (increased attributes, defensive barriers, regeneration), and those that hinder the character (decreased attributes, incapacitation, degeneration). Especially in MMORPGs, beneficial effects are referred to as buffs, and hindering effects are called debuffs.

Acquiring and removing status effects

A status effect in the abstract is a persistent consequence of a certain in-game event or action, and as such innumerable variants exist across the gaming field. Status effects may result from one character performing a certain type of attack on another. Players may acquire status effects by consuming items, casting spells on themselves or each other, activating devices in the world, interacting with NPCs, or remaining in a particular location. Some games offer permanent status effects which persist for an entire level and act as modifications to the game's native difficulty.
