Create a palette
- Open Menu → Colour mapping… and choose Your palettes….
- Use New palette from to copy a built-in palette or one of your own.
- Give it a descriptive name and edit its colours.
- Review the contrast and colour-separation feedback, select the palette in colour mapping and save the model.
Match the kind to the data
Use separate categorical colours for owners or service types. A ramp progresses from light to dark for ordered or numeric values. A through-a-middle palette uses a neutral centre for values on either side of a midpoint. Only suitable palettes are offered for a mapping.
Check readability
The palette editor reports close colour pairs, including a red-green colour-vision comparison, and flags colours too dark for black text. Treat these as practical checks, not a guarantee that every reader can distinguish every value. Keep labels and the legend meaningful as well.
Share with another model
In Revelation, Export writes palettes.json; Import adds palettes from that file. Duplicate names are given a number. Deleting an in-use palette replaces it with a built-in palette.
Palette file downloads depend on the browser environment. In Confluence, do not rely on iframe downloads; transfer the model through its attachment when you need to carry saved palettes to another environment. Import and export of a whole model are described in file workflows.
