Below is an example palette from an example room. The GLOBAL aspects of the palette are color indexes 0 - 15 and 192 - 255.

Color indexes 0 - 15 are, and should always be, the first 15 colors from the default MS-DOS palette. These are used by the TWIGZ Engine for dialogue text colors. Each actor, when talking, has his own dialogue text color. (Note: The Ego is ALWAYS Actor 1, his dialogue text color is always 15).

Color indexes 16 - 191 are reserved for map images, it is important that the map image color count does not exceed 176 colors.

The remaining Color indexes, 192 - 255, are used for inventory pictures, character colors, and other multi-room objects (Note: 255 is reserved for the transparent color).

In summary, no colors should change (except for special circumstances) except for colors 16 - 191.
