official CSS Color Adjustment forced-color-adjust none forced colors background color user-selected palette Canvas system color

💡 Result:

The CSS Color Adjustment specification establishes:

- In **forced-colors mode**, the browser applies the user’s preferred palette to properties including `background-color`. The palette is exposed through CSS system colors. ([w3.org](https://www.w3.org/TR/css-color-adjust-1/?utm_source=openai))
- With the default `forced-color-adjust: auto`, a non-system `background-color` is forced to the system color opposite the text color—`Canvas` opposite `CanvasText`—while preserving the original alpha. ([w3.org](https://www.w3.org/TR/css-color-adjust-1/?utm_source=openai))
- `forced-color-adjust: none` opts that element out of automatic color adjustment, restoring author control. It does **not** make a hard-coded background follow the user’s palette; authors should use it only when they are handling accessibility themselves. ([w3.org](https://www.w3.org/TR/css-color-adjust-1/?utm_source=openai))

So if you want the background to follow the user-selected forced-colors palette, use `Canvas` (and typically `CanvasText` for text), rather than opting out with `forced-color-adjust: none`.

Use a forced-colors system color for the fill

The track remains subject to forced-colors adjustment, which can map its background to Canvas. The fill uses forced-color-adjust-none, so it preserves --primary. A user-selected palette can make Canvas match that preserved color, hiding partial download progress.

Use Highlight for the fill in forced-colors mode.

Update the progress fill in ProviderSetupSection to use the system Highlight
color in forced-colors mode, while preserving its existing default styling and
animation behavior.
