Re: [csswg-drafts] [css-color-4][css-color-5] Allow `<alpha-value>` to be `none` in `<color()>` (#7397)

Sorry, not sure what your actual question is.

CSS Color 4 has a definition for [the `color()` function](https://drafts.csswg.org/css-color-4/#color-function).

CSS Color 5 expands that definition, adding two things:

1. [Relative Color Syntax](https://drafts.csswg.org/css-color-5/#relative-color-function) (the `[from <color>]?` part)
2. [Custom color spaces](https://drafts.csswg.org/css-color-5/#custom-color) (via [`@color-profile`](https://drafts.csswg.org/css-color-5/#at-profile)

The Color 4 definition is the current, stable implementation target in browsers. Safari implements RCS, and BFO Publisher implements custom color spaces.
