For each material ID in GeoDict, a color can be selected for visualization. These colors are set globally in GeoDict and are not saved in the structure file. For each material in the material database, also a corresponding color is stored. In the following, it is described how to use these stored material colors for display.

The color of a material in GeoDict can be changed through the Color and Visibility Settings dialog by selecting Settings → Color & Visibility Settings… in the menu bar, or by clicking the corresponding icon in the toolbar. This opens the Color & Visibility Settings dialog, which can also be accessed directly from the sidebar on the right of the user interface.

The Color and Visibility Settings dialog shows the colors currently assigned to the Material IDs and the Constituent Materials.

To use the colors defined in the GeoDict Material Database, click Load Preset and then, choose Material database in the Load Color Preset dialog. Confirm the choice with OK and close the Color & Visibility Settings with the Close button in the top right.

For example, the preset color for Glass in the material database is a light grey, as shown here.
