Unprefixed print-color-adjust

The print-color-adjust allows adjusting colors in printed web pages. This is the same as Chromium's already-supported -webkit-print-color-adjust, but with a standardized name.

concepts

  1. print-color-adjust

    print-color-adjust ships unprefixed. The legacy -webkit-print-color-adjust alias still works.

  2. Dark-mode print

    The canonical motivation: a dark-mode boarding pass whose status badges are load-bearing. Two side-by-side previews — economy strips them, exact keeps them.

  3. Print Preview Lab

    Two boarding-pass panes side by side — one driven by the unprefixed property, one by the legacy -webkit- alias — with a mode switcher and a Print button that proves they end up identical.

  4. Migration Audit

    Paste any CSS stylesheet. The auditor finds every -webkit-print-color-adjust usage, shows which are prefixed-only vs already migrated, and generates migrated CSS — keeping both properties during the transition and flagging selectors ready for webkit cleanup.

why it shipped

This CSS property should appear in unprefixed form, to match the standard.
