⚠ NEVER add commits to this pull request.

🤖 This pull request was automatically created to facilitate human review of @webref/css changes triggered by curated data at f3606e4.

🧐 Please review the diff below and version numbers. If all looks good, merge this pull request to release the changes to npm.

📦 Latest released @webref/css package was v6.20.4. Merging this pull request will release v6.20.5. Make sure that the bump is the right one for the changes.

✍ If any change needs to be made before release, do not add a commit to this pull request. Changes should rather be handled in a separate pull request and pushed to the main branch. You may leave this pull request open in the meantime, or close it. The pre-release job will automatically update this pull request or create a new one once the updates have made their way to the main branch.

🛈 The actual change introduced by this pull request is a version bump in packages/css/package.json. You do not need to review that change. The bumped version is not the version that will be released when this pull request is merged, but rather the version that will be released next time.

The white point is D50, the same as is used by CIE Lab. Thus, conversion to CIE Lab does not require the chromatic adaptation step. The ProPhoto RGB space uses hyper-saturated, non physically realizable primaries. These were chosen to allow a wide color gamut and in particular, to minimize hue shifts under tonal manipulation. It is often used in digital photography as a wide gamut color space for the archival version of photographic images. The prophoto-rgb color space allows CSS to specify colors that will match colors in such images having the same RGB values. The ProPhoto RGB space was originally developed by Kodak and is described in [Wolfe]. It was standardized by ISO as [ROMM],[ROMM-RGB].
