vdoc: which color for (dark mode) theme-color?

[yochem]

Describe the feature

Currently, the theme-color meta tag is set to #FFFFFF, even when the user switches to dark mode using the toggle button. In my opinion, it would look pretty if the theme color is set to the TOC bg color or the main page bg color. Here are some screenshots on MacOS Safari:

Use Case

It looks more modern and changing theme color based on dark/light mode seems like the right choice.

Proposed Solution

document.querySelector("meta[name='theme-color']").setAttribute(
    "content",
    isDarkModeEnabled ? '#1a202c' : '#ffffff'
);

In ./cmd/tools/vdoc/theme/doc.js

Other Information

Safari on Mac is currently the only desktop browser that support theme-color. It is mostly supported on browsers on phones. On mobile devices, the doc web page has a header on top of the page. It will probably look best if on mobile, the theme-color is set to the color of this header.

I'm interested to hear from you which color you would prefer (desktop/mobile, dark/light). Let me know, and then I'll look at implementing this.
