As someone who prefers a solid color background, I’m always surprised by how often this simple preference leads me into bizarre rabbit holes.

Some additional examples beyond the OP:

- In the latest macOS, trying to set a custom solid color background just gives you a blinding white screen (see: https://discussions.apple.com/thread/256029958?sortBy=rank).

- GNOME removed all UI controls for setting solid color backgrounds, but still technically supports it if you manually set a bunch of config keys — which seem to randomly change between versions (see: https://www.tc3.dev/posts/2021-09-04-gnome-3-solid-color-bac...).

The pattern here seems pretty clear: a half-baked feature kept alive for niche users, rather than either properly supporting or cleanly deprecating it. Personally, I’d love to simply set an RGB value without needing to generate a custom image. But given the state of things, I’d rather have one solid, well-maintained wallpaper system than flaky background color logic that’s barely hanging on.
