Diagram news: By now, there is an exemplary dark mode edition (for Anduril 2 release 2025-07-07 only):
With this dark mode edition, the idea is not only to demonstrate the color setting possibilities that come with the diagram, but also to visually emphasize the triad of basic use, Simple UI, and Advanced UI. This triad may be even more discernible in dark mode.
For those interested, in the TEX source file the colors are mainly defined in the color settings within the preamble, as can be seen for the generic diagram and in comparison for the dark mode edition.
Anyway, the diagram now also comes in black. 
This dark mode edition has been in the making at my end for a while now. Coincidentally, someone over at Reddit just very recently had a similar idea and posted a dark mode version of the diagrams by @containerfan. So I take it that the dark mode style may well prove to be useful.
Edit 2025-08-12: Updated dark mode diagram image following a new release.
Edit 2025-08-15: Updated dark mode diagram image to reflect yesterday’s new release. Following TK’s manual, I have added a colored emphasis on configuring Simple UI via Advanced UI (via Simple UI Config and via Inherited by Simple UI). By now, this is basically what I had in mind for a visualization in dark mode. If someone is interested and has further ideas on this and the use of colors, just let me know.
