cdoublev has just created a new issue for https://github.com/w3c/csswg-drafts:
== [css-color-4] Allow `none` in all legacy color function syntaxes ==
> [4.3. "Missing"/none Color Components](https://drafts.csswg.org/css-color-4/#missing)
>
> If a color with a [missing component](https://drafts.csswg.org/css-color-4/#missing-color-component) is serialized or otherwise presented directly to an author, then for [legacy color syntax](https://drafts.csswg.org/css-color-4/#legacy-color-syntax) it represents that component as a zero value
The value definition of legacy `<rgb()>`, `<rgba()>`, `<hsl()>`, and `<hsla()>`, do not allow `none`:
```
rgb() = rgb( <percentage>#{3} , <alpha-value>? ) | rgb( <number>#{3} , <alpha-value>? )
hsl() = hsl( <hue>, <percentage>, <percentage>, <alpha-value>? )
```
