Colour Palettes
To save effort and promote consistency, you can re-use palettes of colours that you have already created. In addition to the palettes you might save, several predefined palettes are supplied with the application. These are installed in the application folder and are available to all projects.
To select a colour palette
- Open the Colours and Colour Sets or Hatch Sets form.
- Click on the Select button.
- Select a palette set from the list displayed in the Colour Palette dialog.
When you click the Select button in an Edit Colour Set or Edit Hatch Set form, a range of system palettes are available for selection. The palettes accessed by the application are located in your User Profile Folder at:
%AllUsersProfile%\Micromine\Micromine\Environment\Palettes
If you have created your own palettes, you will need to manually move them into the Palettes folder before you can use them in the application.
You can enter text into the Search box to locate a palette which matches or partially matches a search string.
To differentiate between palettes of the same name in different locations, the filepath of a palette is shown when you hover over the name of the palette:
To save a colour palette
- Create the palette in the main form.
- Click Save and enter a filename. This is the file that will appear in the selection list.
Palettes in the application are grouped into subfolders based on their types. A selection of quick-access palettes are available in the top-level folder. These quick-access palettes are copies of palettes within the subfolders, although some of their names have been changed to make them clearer at the top level.
Where needed for clarity, numbers following the names indicate the number of colours in each palette. The following palettes are included:
| Category | Description |
|---|---|
| CET Perceptual | The University of Western Australia's Centre for Exploration Targeting (CET) provide a collection of perceptually uniform colour palettes, which can be used to display geological, geophysical, and geochemical data that vary over a continuous range. See: CET Perceptual |
| ColorBrewer | A large collection of palettes based on research into map design and readability, including colour-blindness and the ability to survive photocopying. Palettes are grouped into three types: divergent, qualitative and sequential. See: ColorBrewer |
| Perceptually Uniform | Perceptually uniform colour palettes are designed such that the change in colour is perceptually uniform throughout the palette. These palettes are grouped into two types: Large Brightness Range (not recommended for 3D surfaces) and Small Brightness Range (best for 3D surfaces). See: Perceptually Uniform |
| Discrete | Palettes for discrete data such as names or codes. |
| Geologic Standards | Text-only palettes based on colours from various geological standards. |
| Other | Miscellaneous palettes. |
| Point Count | Palettes for displaying the number or frequency of data values falling within a counting neighbourhood. These mostly apply to application functions that use palettes instead of colour sets, but may also be used elsewhere. |
| Ramps | A collection of colour ramps divided into three groups: single colour, two colours and multiple colours. Some two-colour ramps incorporate white as an intermediate colour. |
| Topography | Numeric-only palettes for topographic elevation. |
| User | A location for user-defined palettes. |
If you find yourself regularly using a palette you may prefer to promote it to the top level for quick access. To do so, right-click on the palette and choose Copy to top level from the pop-up menu.
To navigate from a subfolder and move back up to the next level, double-click on the Parent folder icon:
Save Set As

The palettes accessed by the application are located in your User Profile Folder at:
%AllUsersProfile%\Micromine\Micromine\Environment\Palettes
