Just to clarify, this intent proposes to add an `auto` value to
accept-color, that picks up the system accent-color. Do I have that right?

Hey Priya,
Can we make sure to request explicit signals from WebKit? Thanks.
LGTM1 modulo that nit.
Best,
Alex

Summary
This feature empowers web developers to enhance the visual appeal
of their websites by leveraging the operating system's accent
color for form elements. By utilizing the "accent-color" CSS
property, developers can ensure that form elements such as
checkboxes, radio buttons, and progress bars automatically adopt
the accent color defined by the user's operating system. This
feature is an enhancement to existing feature that is already
shipped in Chromium:

WebView application risks
Does this intent deprecate or change behavior of existing APIs,
such that it has potentially high risk for Android WebView-based
applications?
None
Debuggability
When the platform's accent color is utilized for the
"accent-color" CSS property, either due to the absence of a
specified value or when set to "auto," the getComputedStyle() JS
function returns "auto" instead of the actual hexadecimal value of
the color being applied. Related link:
https://github.com/w3c/csswg-drafts/issues/6158
<https://github.com/w3c/csswg-drafts/issues/6158>
Will this feature be supported on all six Blink platforms
(Windows, Mac, Linux, ChromeOS, Android, and Android WebView)?
No
This feature is currently supported on Windows, macOS, and
ChromeOS. Future work for Linux is planned and can be tracked at
the following link: https://issues.chromium.org/issues/391917949
<https://issues.chromium.org/issues/391917949>. Android features a
setting for accent color, and we plan to add support for Android
in the future. The strategy is to release this feature
incrementally, allowing web developers to provide feedback and
assess the necessity of allocating additional resources for other
less requested platforms.
Is this feature fully tested by web-platform-tests
<https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md>?
Yes

Note: The provided links are WPT for the accent-color property,
including scenarios where the value is set to "auto." This feature
relies on the platform's accent color and necessitates a WebDriver
extension to simulate the accent-color property accurately. To
ensure consistent testing with WPT, we would need to look into
WebDriver API to support this functionality properly.
Are there any bugs to track this WebDriver follow-up work?

Anticipated spec changes
Open questions about a feature may be a source of future web
compat or interop issues. Please list open issues (e.g. links to
known github issues in the project for the feature specification)
whose resolution may introduce web compat/interop risk (e.g.,
changing to naming or structure of the API in a
non-backward-compatible way).
