I did not see that AppKit accounts for this, although it does allow control over both the track and thumb color individually, whereas the web platform only allows control over the track color. 2106216 3 lwarlow 2025-03-26 12:54:05 -0700 This seems to work fine if you set `color-scheme: dark` on the element. It's unclear why the background color of the switch would change dependent on the page's background colour? Perhaps AppKits switch is context aware somewhat? Is there a way to opt-out of that by default so the switch acts more like other controls (is light mode by default?)
