Chrome's Built-In EyeDropper API Replaces Complex Color-Picker Workarounds

Chrome and other Chromium-based browsers have included a native EyeDropper Web API called window.EyeDropper since late 2021, eliminating the need for complex canvas or screen-capture workarounds. The API allows users to sample a color from anywhere on their screen — including other apps and the desktop — by delegating the screen-reading task to the operating system rather than the browser sandbox. It returns only a single hex color string, making it deliberately narrow in scope and exempt from the heavy permission prompts required by screen-capture APIs like getDisplayMedia. The feature requires a direct user gesture, such as a click event, to function; calling it from asynchronous chains or on page load will cause it to throw an error. Developers can implement a fully functional eyedropper tool in just a few lines of code, compared to the roughly 150 lines needed for a canvas-based workaround.
