Changing a palette affects the three different layers of a texture. These three layers are: Background, Foreground, and Minor Foreground.
| Palette Value | Description |
|---|---|
| 0 | Default. Access Switch/Card = blue. |
| 1 | All layers become blue. The usual choice to designate certain sprites as Multiplayer-only or DukeMatch-only. |
| 2 | All layers become red. |
| 3 | Null. Assault Troopers will appear as default blue colour. The usual choice to neutralize parallaxed space textures. |
| 4 | All layers become solid black. Defines a mirror as indestructible in EDuke32. |
| 5 | All red colours become brown. |
| 6 | All layers become night vision green. |
| 7 | All layers become yellowish-bronze. |
| 8 | All layers become light green. |
| 9 | Null. Assault Troopers will appear as default blue colour. Default colour of player 1 in Multiplayer modes. |
| 10 | Foreground becomes red. Default colour of player 2 in Multiplayer modes. |
| 11 | Foreground becomes light green. Default colour of player 3 in Multiplayer modes. |
| 12 | Foreground becomes light gray. Default colour of player 4 in Multiplayer modes. |
| 13 | Foreground becomes dark gray. Default colour of player 5 in Multiplayer modes. |

| 21 | Foreground becomes red. Access Switch/Card = red. Assault Trooper becomes Assault Captain (with teleporter/cloaking device). The usual choice to turn Bosses (or Respawned Bosses) into Mini-Bosses (only the Battlelord is usefully compatible with this feature). |
| 22 | Foreground becomes light green (same as 11). |
| 23 | Foreground becomes yellow. Access Switch/Card = yellow. |
