What Bob wrote was that by clicking a button you can choose which system
palette you wish to present (0..3). Many programs allow this.

Programs should allow users to change or configure which system palette to
use. Programmers only have to add in the facility to alter the value of the
default palette and make sure the program menues at least look ok in the
four standard system palettes. Although the programmer has no idea how his
program presents on any user's machine, by using the correct or sensible
palette elements the chances are that his program will display correctly.

Some (eg D-Miner) also allow you to specify a program-specific palette. In
D-Miner the program-specific palette is even passed to external menus (ie
menus that are larger than the main program window and must therefore be
called up as external jobs).
