Switching between dark/light modes and theme at the same time

What I’m trying to do

Find a way of switching between dark and light mode and switching the associated theme at the same time.
For example, for dark mode I prefer to use the Blackbird theme.
For light mode, I love the Primary theme.

Things I have tried

Creating a QuickAdd plugin macro
Creating a Commander plugin macro

I end up with a situation where a macro can bring up the theme selection dialog but then you need to pick the theme manually anyway.

Interesting.
There’s the theme design utilities plugin which allows to toggle between light and dark mode. I never understood why Obsidian adds two buttons to switch theme mode instead to add a simple toggle for the user interface.

However, to switch themes and theme mode at the same time, you’d need a plugin.
