Django admin’s dark theme should set color-scheme property for vanilla HTML components — at Initial Version

Description

The Django admin uses unstyled vanilla HTML widgets for a few scenarios. Currently in the dark theme those elements are displayed with the browser’s default "light" UI – it would better if we instructed the browser to use their dark variant with the CSS color-scheme property.

Here’s an example, where ​color-scheme affects the search field’s clear button color and checkboxes, before/after:

  • For the clear button it’s almost invisible without this so is a clear accessibility issue / WCAG contrast fail
  • For the checkboxes it just looks better.

This also affects file inputs, multi-select widgets, scrollbars, and I’m sure other parts of the UI.

---

My suggested solution would be to add color-scheme: dark at the root level when in dark mode, but it might be worth researching a bit to make sure we use the property as well as possible.
