All features described in CSS Color 4 (https://www.w3.org/TR/css-color-4/) are now enabled! This includes four device-independent color types (lab, Oklab, lch and Oklch), the color() function and user-defined color spaces for gradients and animations. The incredibly useful color-mix() function from CSS Color 5 (https://www.w3.org/TR/css-color-5/#color-mix) has also been included as a bonus!
In order to fully take advantage of HD color displays, allow for more robust photo editing, to improve tools for web authors and to finally rid the world of ugly, dark gradients many new features have been added to the CSS Color specification. It's high time we implemented them in Chromium.
