The color name database provides a mapping between ASCII color names and RGB color values. It is useful for increasing the portability of color programs. The input source for the database is in \fI__RGB_DB__.txt\fP. \fIrgb.txt\fP is compiled into the __RGB_DB_TYPE__ files .IR "__RGB_DB_FILES__" . When the server first starts up, it consults the contents of these files to build an internal representation of their contents. This internal representation is consulted to map color names to color values. .PP .B rgb uses the default color name database of \fI__RGB_DB__.txt\fP. .SH OPTIONS .IP "\fIdbname" 1i Color name database. .SH EXAMPLES example% rgb rgb < __RGB_DB__.txt .PP example% cat __RGB_DB__.txt .SH FILES .PD 0 .TP 30 .B __RGB_DB__.txt color name database source.
