Re: [csswg-drafts] [css-color] Mitigating fingerprinting for AccentColor/AccentColorText (#10372)

> on windows we don't expose the system accent color, currently.

I believe that what @alisonmaher and/or @padmapriyap1 want to implement in chromium would expose the system accent color on windows.

> Firefox was already shipping similar colours for e.g. selection (Highlight/HighlightText) which already exposed / were derived from the system accent color

I believe that we might still be leaking the system accent color on macos in chromium via -webkit-focus-ring-color because nobody has made a big stink about it yet, but I could see us patching that like WebKit did eventually. We don't use the accent color for anything on any other platforms so I don't think we can use this macos behavior as precedent to start leaking for the other platforms either.

> the way to fix it would be returning a hard-coded color not only for accent color, but also for Highlight / SelectedItem / etc

This sounds to me like we should give up on AccentColor/AccentColorText unless it would be useful for installed websites to have access to the system accent color and we can get confirmation that fingerprinting is OK in those cases.
