How to Change Colors in XEmacs

(by Justine Ehlers)
About Colors:

The default background that XEmacs comes with "out of the box" is gray. However, a gray background makes it harder to see the lighter colors. That's why I changed the backgrounds to black.

Note: If you choose "Save Options" from the "Options" pulldown, your colors are NOT saved (everything else is). XEmacs 20.3 moved "officially" changing and saving the colors to the "Customize" area. See below, #2 on "How to Change Colors".
How to Change Colors:

1. Quick, No Changes Are Saved
* Go to the "Options" pulldown (top of XEmacs), select "Browse Faces". This gives you a list of what you can change.
* Click on the foreground color you'd like to change.
* Type "Shift key"f for F.
* Notice at the bottom of your XEmacs that it'll prompt you for the new color. Backspace over the color name.
* You can either type a color name or hit the "tab key". Hitting the "tab key" gives you a five page list of colors you can choose. Choose a color. XEmacs updates the colors.
* You can change the background color. Click on the background color you'd like to change.
* Type "Shift key"b for B.
* Proceed the same as for the foreground color.
2. Slower, Changes Are Saved
* Go to the "Options" pulldown (top of XEmacs), select "Customize" then "Face..."
* Notice at the bottom of your XEmacs that it'll prompt you to choose what you want to change. "Customize face: (default all)" Hit the "Enter key" to choose all. (If you know the name, you can type the name to just change the one color.)
* You get a list of what you can change. Middle click on [Show] to see the items to change.
* Select by clicking on the [ ] at the beginning of the line. Hit "Enter key" to select it. Hit "Enter key" to deselect. (The "Enter key" is a toggle.)
* Backspace over the color.
* Choose another one. Notice it'll show you immediately what it looks like.
* If you like it, you can save one of two ways: (1) Go back to the top and click on the "Save" button. (2) Go to the "Custom" pulldown (top of XEmacs) and choose "Save".

Note: since I don't use xemacs, I don't know if this will change more than the foreground/background colors.

terminal-colors.d

TERMINAL_COLORS.D(5)                                             terminal-colors.d                                            TERMINAL_COLORS.D(5)

NAME

       terminal-colors.d - Configure output colorization for various utilities

SYNOPSIS

       /etc/terminal-colors.d/[[name][@term].][type]

DESCRIPTION

       Files in this directory determine the default behavior for utilities when coloring output.

       The name is a utility name.  The name is optional and when none is specified then the file is used for all unspecified utilities.

       The term is a terminal identifier (the TERM environment variable).  The terminal identifier is optional and when none is specified then the
       file is used for all unspecified terminals.

       The type is a file type.  Supported file types are:

       disable
              Turns off output colorization for all compatible utilities.

       enable Turns on output colorization; any matching disable files are ignored.

       scheme Specifies colors used for output.  The file format may be specific to the utility, the default format is described below.

       If there are more files that match for a utility, then the  file  with  the  more  specific  filename  wins.   For  example,  the  filename
       "@xterm.scheme" has less priority than "dmesg@xterm.scheme".  The lowest priority are those files without a utility name and terminal iden-
       tifier (e.g. "disable").

       The user-specific $XDG_CONFIG_HOME/terminal-colors.d or $HOME/.config/terminal-colors.d overrides the global setting.

EXAMPLES

       Disable colors for all compatible utilities:
              touch /etc/terminal-colors.d/disable

       Disable colors for all compatible utils on a vt100 terminal:
              touch /etc/terminal-colors.d/@vt100.disable

       Disable colors for all compatible utils except dmesg(1):
              touch /etc/terminal-colors.d/disable

              touch /etc/terminal-colors.d/dmesg.enable

DEFAULT SCHEME FILES FORMAT

       The following statement is recognized:

              name color-sequence

       The name is a logical name of color sequence (for example "error").  The names are specific to the utilities.  For more details always  see
       the COLORS section in the man page for the utility.

       The color-sequence is a color name, ASCII color sequences or escape sequences.

   Color names
       black,  blink,  blue,  bold,  brown,  cyan,  darkgray,  gray, green, halfbright, lightblue, lightcyan, lightgray, lightgreen, lightmagenta,
       lightred, magenta, red, reset, reverse, and yellow.

   ANSI color sequences
       The color sequences are composed of sequences of numbers separated by semicolons.  The most common codes are:

               0   to restore default color
               1   for brighter colors
               4   for underlined text
               5   for flashing text
              30   for black foreground
              31   for red foreground
              32   for green foreground
              33   for yellow (or brown) foreground
              34   for blue foreground
              35   for purple foreground
              36   for cyan foreground
              37   for white (or gray) foreground
              40   for black background
              41   for red background
              42   for green background
              43   for yellow (or brown) background
              44   for blue background
              45   for purple background
              46   for cyan background
              47   for white (or gray) background

   Escape sequences
       To specify control or blank characters in the color sequences, C-style -escaped notation can be used:

              a   Bell (ASCII 7)
                 Backspace (ASCII 8)
              e   Escape (ASCII 27)
              f   Form feed (ASCII 12)
              
   Newline (ASCII 10)
              
   Carriage Return (ASCII 13)
              	   Tab (ASCII 9)
              v   Vertical Tab (ASCII 11)
              ?   Delete (ASCII 127)
              \_   Space
              \   Backslash ()
              ^   Caret (^)
              #   Hash mark (#)

       Please note that escapes are necessary to enter a space, backslash, caret, or any control character anywhere in the string, as  well  as  a
       hash mark as the first character.

       For example, to use a red background for alert messages in the output of dmesg(1), use:

              echo 'alert 37;41' >> /etc/terminal-colors.d/dmesg.scheme

   Comments
       Lines where the first non-blank character is a # (hash) are ignored.  Any other use of the hash character is not interpreted as introducing
       a comment.

FILES

       $XDG_CONFIG_HOME/terminal-colors.d
       $HOME/.config/terminal-colors.d
       /etc/terminal-colors.d

ENVIRONMENT

       TERMINAL_COLORS_DEBUG=all
              enables debug output.

COMPATIBILITY

       The terminal-colors.d functionality is currently supported by all util-linux utilities which provides colorized output.  For  more  details
       always see the COLORS section in the man page for the utility.

AVAILABILITY

       terminal-colors.d  is  part  of  the  util-linux package and is available from Linux Kernel Archive <https://www.kernel.org/pub/linux/utils
       /util-linux/>.

util-linux                                                         January 2014                                               TERMINAL_COLORS.D(5)
