page color metadata 🎨

[vincent-peugnet]

Another idea of metadata for pages: a color setting ! 🤯

It could be set in page edit view thanks to the HTML color picker.

Then it would create a dedicated CSS var called --page-color or something like this.

It would be set as data-color on links, so that users could use it to color links with css. 😋 (this do not work yet?, see mdn doc, but there is an interesting solution)

Another benefit could be to color the map markers according to page color.

This could also be seen in the graph view by coloring the nodes.

It's a simpler, more flexible but limited alternative to #321 concept.

The default color would use a hash of the page ID. Or a default one set in admin ?
