The color customizer does not affect the colors of DECterm
               windows, set up as described previously. To affect
               the colors of DECterm windows, copy the DECterm resource
               specifications from the file DXMDEFAULTS.DAT and add
               them to the DECterm resource defaults file DECW$USER_
               DEFAULTS:DECW$TERMINAL_DEFAULT.DAT. For example, add the
               following lines to the DECterm resource defaults file:

                .
                .
                 DECW$TERMINAL.main.terminal.background: DXmDynamicTerminalBackground
                 DECW$TERMINAL.main.terminal.foreground: DXmDynamicTerminalForeground

               This will allow the DECterm window colors to be customized
               with the color customizer.
