Release Note Request (optional, but appreciated)
[Why is this notable]:

Firefox now supports the color functions from the color (level 4) specification. This includes the lab(), lch(), oklab(), oklch() and color() functions.

Added to the Nightly 113 relnotes to ride the trains to release. Also adding the dev-doc-needed keyword as I assume we'll need some MDN docs on this as well.

Given this, let's close this tracking bug for clarity, to avoid confusing users/developers with the impression that "Implement CSS Color Module Level 4" remains something to-be-done in the future.

(We can still use this for tracking as-needed with dependencies etc. Tiaan / emilio: if I'm misunderstanding and there are still substantial portions of css-color-4 that are un-implemented & merit keeping this metabug in an "open" state, feel free to reopen if appropriate.)

Hi Ryan, taking a look for MDN docs additions. We have already have reference pages for the functional notation:

• lab(), lch(), oklab(), oklch(), color()

These pages were added / updated in https://github.com/mdn/content/pull/25015 for Fx111. Is there anything else outstanding to be documented on MDN relevant to this bug? I can only see BCD and a note for developers that the pref layout.css.more_color_4.enabled is enabled by default.

Hi Tiann, do the MDN docs linked from comment 5 look sufficient to you?

That's great. Follow-up work for browser compat data and release notes for developers can be tracked in the following GitHub issue: https://github.com/mdn/content/issues/26147

CSS color level 4 changes does not depend on the graphics side of Display P3 rendering. Removing the dependency.
