RGB(1) X Version 11 (Release 4) RGB(1)
NAME
rgb - convert a rgb spec file to ndbm files
SYNOPSIS
rgb
DESCRIPTION
rgb reads the standard input and writes ndbm files
/usr/lib/X11/rgb.pag and /usr/lib/X11/rgb.dir. These files
are suitable for use by the X server.
The expected use of rgb is to support custom modification of
/usr/lib/X11/rgb.txt. Typically, it is used by invoking:
rgb < [path]rgb.txt
NOTE: You must have permission enabling you to write the
files in /usr/lib/X11. Typically, this means running as the
Super-User.
RGB.TXT FORMAT
The rgb.txt file is a list of color specifications, one
specification per line. A specification is
RedValue GreenValue BlueValue Color_name
Values are separated by whitespace. For the purposes of
this man page, whitespace means any series of spaces and/or
tabs. The Color_name starts from the first non-whitespace
character following the third value and extends to the
newline, including trailing whitespace, which is
significant. Imbedded whitespace is allowed. For example,
25 25 112 midnight blue
64 224 208 turquoise
describes colors "midnight blue" and "turquoise" assuming
there is no trailing whitespace after those strings. The
space in "midnight blue" is significant.
The results of feeding rgb invalid data are not defined.

BUGS
About the only help you get in case of an error is:
syntax error on line <x>
rgb always writes to /usr/lib/X11.
