X11 color names

When computed in the X Window System, X11 color names are represented in a plain text file that maps specific strings to RGB color values. It traditionally comes with every X11 installation, hence its name, and is usually located at /lib/X11/rgb.txt. The web color list is derived from this, but differs in some color names. Color names are not standardized by Xlib or the X11 protocol. The list shows no continuity in the values ​​or names of the selected colors, and some color triplets have multiple names. Despite this, graphic designers and others have gotten used to it, making it nearly impossible to come up with another list. In previous versions of X11 (before the introduction of Xcms), server implementers were required to modify the RGB values ​​in the reference color database to account for gamma correction. Starting with X.Org version 7.4, the rgb.txt file is no longer included in the cumulative version and the list is integrated directly into the server. The optional xorg/app/rgb module contains the standalone rgb.txt file. The list first shipped with X10 version 3 (X10R3) on June 7, 1986, after Jim Gettys registered it with RCS in 1985. The same list was on X11R1 on September 18, 1987. Approximately complete list , as available today, ships with the X11R4 on January 29, 1989, with major additions from Paul Ravelling (who added colors based on paint flakes from Sinclair Paints), John C. Thomas (who added colors based on a set of 72 Crayola crayons I kept on hand) and Jim Fulton (who voted for entries to create the X11R4 list). The design at the time used DEC VT240 terminals, so it would work with that device. In some applications, multipart names are written with spaces, in others they are concatenated, often case sensitive. They are generally case-insensitive matched, and the X server source contains separate aliases for most inputs; This article uses spaces and capitals unless variations with spaces are specified in the actual code.
