* add PaletteManager
* add hint for "external" palette-names
* macro utility, for local \import only
this tiddler is never meant to be tagged $:/tags/Macro
contains only a colour macro which allows to call `<<colour "...">>` within a tiddler and get the parameter-name instead of the resolved color
used in the PaletteManager to reveal the original color below the color that just uses its color with the colour macrocall
example:
```
\define get-real-index(string)
\import $:/core/macros/utils
<$wikify $name="result" text="""$string$"""> <- does the "colour" macrocall, but the one that returns the parameter name
<<result>>
</$wikify>
\end
<$set name="color" value={{{ [{$:/palette}getindex[color-of-interest]] }}}>
-> <<colour primary>>
<$wikify name="real-color-index" text="""<$macrocall $name="get-real-index" string=<<color>>/>""">
<<real-color-index>> -> primary
...
