Hello Eitan, in Dublin we talked about a plan to turn on high contrast mode / forced colors for a specific tab/page. I can't remember if there are already a (meta) Bugzilla bug or a Jira ticket for it? Or maybe some rough document that lays out a plan?

If there are none, I'd like to file bug for the "internal" work, e.g. have a flag on BrowsingContext so we can do something similar to what we have for color-scheme simulation https://searchfox.org/mozilla-central/rev/cb5faf5dd5176494302068c553da97b4d08aa339/dom/chrome-webidl/BrowsingContext.webidl#210

[SetterThrows] attribute PrefersColorSchemeOverride prefersColorSchemeOverride;

There is no bug or written plan for this as far as I am aware. An addition to BrowsingContext is a good place to start indeed.

Alright, I filed Bug 1916591 (and Bug 1916589) for the flags
