Papal conclave

A papal conclave is a meeting of the College of Cardinals convened to elect a new Bishop of Rome, also known as the Pope. The pope is considered by Roman Catholics to be the apostolic successor of Saint Peter and earthly head of the Roman Catholic Church. The conclave has been the procedure for choosing the pope for almost a thousand years, and is the oldest ongoing method for choosing the leader of an institution.

A history of political interference in papal selection and consequently long vacancies between popes, culminating in the interregnum of 1268–1271, prompted Pope Gregory X to decree during the Second Council of Lyons in 1274 that the cardinal electors should be locked in seclusion cum clave (Latin for "with a key") and not permitted to leave until a new Bishop of Rome had been elected. Conclaves are now held in the Sistine Chapel of the Apostolic Palace.

Since the Apostolic Age, the Bishop of Rome, like other bishops, was chosen by the consensus of the clergy and laity of the diocese. The body of electors was more precisely defined when, in 1059, the College of Cardinals was designated the sole body of electors. Since then, other details of the process have developed. In 1970, Pope Paul VI limited the electors to cardinals under 80 years of age. The current procedures were established by Pope John Paul II in his apostolic constitution Universi Dominici gregis as amended by motu proprios of Pope Benedict XVI dated 11 June 2007 and 25 February 2013. A two-thirds supermajority vote is required to elect the new pope, which also requires acceptance from the person elected.

Shades of white

Shades of white are colors that differ only slightly from pure white. Variations of white include what are commonly termed off-white colors, which may be considered part of a neutral color scheme.

In color theory, a shade is a pure color mixed with black (or having a lower lightness). Strictly speaking, a “shade of white” would be a neutral gray. This article is also about off-white colors that vary from pure white in hue, and in chroma (also called saturation, or intensity).

Colors often considered "shades of white" include, cream, eggshell, ivory, Navajo white, and vanilla. Even the lighting of a room, however, can cause a pure white to be perceived as off-white.

Off-white colors were pervasively paired with beiges in the 1930s, and especially popular again from roughly 1955 to 1975.

Whiteness measures the degree to which a surface is white in colorimetry.

Web colors

Below is a chart showing the computer web color shades of white. An achromatic white is a white color in which the red, green, and blue codes are exactly equal. The web colors white and white smoke are achromatic colors. A chromatic shade of white is a white color in which the red, green, and blue codes are not exactly equal, but are close to each other, which is what makes it a shade of white.

X11 color names

In computing, on the X Window System, X11 color names are represented in a simple text file, which maps certain strings to RGB color values. It is shipped with every X11 installation, hence the name, and is usually located in <X11root>/lib/X11/rgb.txt. The web colors list is descended from it.

Color names are not standardized by Xlib or the X11 protocol. The list does not show continuity either in selected color values or in color names, and some color triplets have multiple names. Despite this, graphic designers and others got used to them, making it practically impossible to introduce a different list. In earlier releases of X11 (prior to the introduction of Xcms), server implementors were encouraged to modify the RGB values in the reference color database to account for gamma correction.

The list first shipped with X10 release 3 (X10R3) on 7 June 1986, having been checked into RCS by Jim Gettys in 1985. The same list was in X11R1 on 18 September 1987. Approximately the full list as is available today shipped with X11R4 on 29 January 1989, with substantial additions by Paul Ravelling (who added colors based on Sinclair Paints samples), John C. Thomas (who added colors based on a set of 72 Crayola crayons he had on hand) and Jim Fulton (who reconciled contributions to produce the X11R4 list). The project was running DEC VT240 terminals at the time, so would have worked to that device. As of X.Org Release 7.4 rgb.txt is no longer included in the roll up release, and the list is built directly into the server. The optional module xorg/app/rgb contains the stand-alone rgb.txt file.
