Re: [csswg-drafts] [css-color-adjust] Allow authors do define custom `color-scheme` values. (#9660)

> ([#](https://github.com/w3c/csswg-drafts/issues/9660#issuecomment-1841452919)) What I still don't actually understand, tho, is what your original example is intending to do. I don't see anything activating a color scheme, nor any definition of what those three custom color schemes are.

Activation: 
- Web Preferences API, where you set this on `:root`
- Author setting `color-scheme: --solarized-dark` on an element.

> ([#](https://github.com/w3c/csswg-drafts/issues/9660#issuecomment-1841452919)) Are they intended to be literally meaningless outside of their ability to trigger schemed-color()?

No. I like what you proposed [here](https://github.com/w3c/csswg-drafts/issues/9660#issuecomment-1834713634), in which an author can define a new color scheme and set the system colors. The minimum required descriptors are only the `base-scheme`, the maximum required descriptors are the minimum + all system colors

```css
/* Bare minimum custom color scheme */
@color-scheme --custom-minimum {
  base-scheme: dark;
}

/* Fully fledged custom color scheme */
@color-scheme --solarized-dark {
  base-scheme: dark;
  AccentColor: …;
  AccentColorText: …;
  ActiveText: …;
  ButtonBorder: …;
  ButtonFace: …;
  ButtonText: …;
  Canvas: …;
  CanvasText: …;
  Field: …;
  FieldText: …;
  GrayText: …;
  Highlight: …;
  HighlightText: …;
  LinkText: …;
  Mark: …;
  MarkText: …;
  VisitedText: …;
}
```

I see where [my reply](https://github.com/w3c/csswg-drafts/issues/9660#issuecomment-1839810219) could be misinterpreted as the first code snippet echos what I initially had in mind … but that initial thought has evolved as this thread grew. The second example in [that comment](https://github.com/w3c/csswg-drafts/issues/9660#issuecomment-1839810219) has the full picture, and incorporates your proposal _(as also detailed in the code snippet in this comment)_ … I think we’re thinking the same on this?
