There’s a bit more to it than that because palette colours can indirect through
to other colours (e.g. in the default “Vanilla” palette, the colour
"blockquote-bar” is set to "<<colour muted-foreground>>”).
But, it turns out that the core erroneously uses the above technique in a
recent update to the framed editor:

<https://github.com/Jermolene/TiddlyWiki5/blob/master/core/modules/editor/engines/framed.js#L45>
https://github.com/Jermolene/TiddlyWiki5/blob/master/core/modules/editor/engines/framed.js#L100
<https://github.com/Jermolene/TiddlyWiki5/blob/master/core/modules/editor/engines/framed.js#L100>
I’ve raised a ticket proposing that we add a core API for obtaining palette
values, and then use it to correct those cases.
