-@item --disassembler-color=[color|extended-color|off]

-@option{color} argument adds color using simple terminal colors.
-Alternatively the @option{extended-color} argument will use 8bit
-colors, but these might not work on all terminals.

+Enables or disables the use of colored syntax highlighting in
+disassembly output.  The default behaviour is determined via a
+configure time option.  Note, not all architectures support colored
+syntax highlighting, and depending upon the terminal used, colored
+output may not actually be legible.

+The @option{on} argument adds colors using simple terminal colors.
+
+The @option{terminal} argument does the same, but only if the output
+device is a terminal.
+
+The @option{extended-color} argument is similar to the @option{on}
+argument, but it uses 8-bit colors.  These may not work on all
+terminals.
 
-If this option is not specified then the default is to enable color
-output if displaying to a terminal, but not otherwise.
+The @option{off} argument disables colored disassembly.
