Hi Mike, Yes, the I2S proposes using the system accent color when the value is set to "auto". To clarify, "auto" is also the default option if no value is provided. Therefore, if the accent-color is not explicitly set, the form elements will automatically use the system accent color by default.

Learn why this is important<https://aka.ms/LearnAboutSenderIdentification> Just to clarify, this intent proposes to add an `auto` value to accept-color, that picks up the system accent-color.

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: https://groups.google.com/a/chromium.org/g/blink-dev/c/WwYkLjbGhoA Blink component Blink>CSS<https://issues.chromium.org/issues?q=customfield1222907:%22Blink%3ECSS%22> Search tags accent-color<http:///features#tags:accent-color>, accent<http:///features#tags:accent>, color<http:///features#tags:color>, system accent color<http:///features#tags:system%20accent%20color> TAG review None TAG review status Not applicable Risks Interoperability and Compatibility None Gecko: Shipped/Shipping Firefox currently supports this feature on Mac and Linux platforms. WebKit: No signal Web developers: No signals Other signals: 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 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. 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 - https://wpt.fyi/results/css/css-ui/accent-color-visited.tentative.html - https://wpt.fyi/results/css/css-ui/accent-color-parsing.html - https://wpt.fyi/results/css/css-ui/accent-color-computed.html - https://wpt.fyi/results/css/css-typed-om/the-stylepropertymap/properties/accent-color.html - https://wpt.fyi/results/css/css-ui/animation/accent-color-interpolation.html 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?
