A colour palette is a data tiddler that supplies a CSS colour value, such as yellow or #fe0, for each of several colour names, like this:
page-background: #fe0
table-border: #ccc
...Several palettes form part of the core. The system tiddler $:/palette always contains the title of the currently selected palette tiddler. You can change a palette using the palette button, found on the "Tools" tab in the sidebar.
To retrieve the value of a named colour from the current palette, e.g. for use in a stylesheet tiddler, use the colour macro:
<<colour page-background>>Palette tiddlers should have the following fields:
| Name | Value |
|---|---|
| title | Typically starting with $:/ |
| type | application/x-tiddler-dictionary |
| tags | $:/tags/Palette |
| name | Displayed in the palette browser |
| description | Displayed in the palette browser |
| text | name: value colour definitions |
