When this property is set to true, the terminal color map can be set using either the ReGIS S(M) command or the restore color table (DECRSTS) control function. When this is set to false, Reflection does not change the color table in response to these commands.
Reflection always allows the color table to be changed as a result of displaying a sixel, regardless of the value of AllowColorTableChanges. The default value is true.
