Hereby: *Blink component* Blink>DarkMode *TAG review* CSS Color Adjust Level 1 has already seen a TAG review, but (re)inclusion of the "only" keyword was not part of that: https://github.com/w3ctag/design-reviews/issues/583 We're still pursuing some additions for a more complete developer story (e.g. https://github.com/w3c/csswg-drafts/issues/6664) and will request review after that. *TAG review status*Not applicable *Interoperability and Compatibility* *Gecko*: No signal *WebKit*: No signal, although Web contents in Apple Mail on iOS supports a force dark mode. *Web developers*: Mixed: we've received positive feedback regarding the decrease in cost of providing a dark mode with the availability of a per-element opt-out, but have also heard concerns about the quality of the darkening algorithms. This experiment will allow us to gather more data on both. *Is this feature fully tested by web-platform-tests?* Yes, parsing tests are included in //css/css-color-adjust/. *Requires code in //chrome?* No. Thanks, Peter > > On Tue, Oct 5, 2021 at 10:18 PM Peter Beverloo <pe...@chromium.org> wrote: > >> *Contact emails* >> futh...@chromium.org, p...@chromium.org, pe...@chromium.org >> >> *Spec* >> https://drafts.csswg.org/css-color-adjust/#color-scheme-prop >> >> *Summary* >> This Origin Trial covers two pieces of related functionality: >> >> First, websites that decide to participate in this trial will have their >> appearance algorithmically adjusted to be darkened, and thus appropriate >> for display whilst a device is in Dark Mode.
