A colour palette is a [[data tiddler|DataTiddlers]] 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 [[$:/palette]] always contains the title of the currently selected palette tiddler.
|
|
|
|
To retrieve the value of a named colour from the current palette, e.g. for use in a stylesheet tiddler, use the [[colour macro|$:/core/macros/CSS]]:
|
|
|
|
```
|
|
<<colour page-background>>
|
|
```
|
|
|
|
Palette tiddlers should have the following fields:
|
|
|
|
|!Name |!Value |
|
|
|title |Typically starting with `$:/` |
|
|
|type |`application/x-tiddler-dictionary` |
|
|
|tags |`$:/tags/Palette` |
|
|
|description |Displayed in the palette browser |
|
|
|text |`name: value` colour definitions |
|
|
|
|
By convention, each [[theme|Themes]] provides a default colour palette in the tiddler [[$:/config/DefaultPalette]]. Thus, setting the tiddler [[$:/theme]] to the string `$:/config/DefaultPalette` will revert to the palette packaged with the current theme (as long as it hasn't been redefined, since it is a shadow tiddler).
