Send a tweet to using the hashtag #EyeDropper and let us know where and how you're using it. # Show support for the APIĪre you planning to use the EyeDropper API? Your public support helps the Chromium team prioritize features and shows other browser vendors how critical it is to support them. Glitch works great for sharing quick and easy repros. Be sure to include as much detail as you can, simple instructions for reproducing, and enter Blink>Forms>Color in the Components box. # Report a problem with the implementationĭid you find a bug with Chromium's implementation? Or is the implementation different from the spec? File a bug at. Is there something about the API that doesn't work like you expected? Or are there missing methods or properties that you need to implement your idea? Have a question or comment on the security model? File a spec issue on the API's GitHub repo, or add your thoughts to an existing issue. The Chromium team wants to hear about your experiences with the EyeDropper API. 
Finally, users are able to cancel the eyedropper mode at any time (by pressing the esc key). There's also a delay between when the eyedropper mode starts and when the user can select a pixel to ensure the user has had time to see the magnifying glass. This is why the normal mouse cursor disappears after a short delay and the dedicated user interface appears instead. To help users notice the eyedropper mode easily, browsers are required to make the mode obvious. So the eyedropper cannot be used in the background without the user noticing it. The promise returned by open() only resolves to a color value in response to a user action (clicking on a pixel). Second, no pixel information can be retrieved without user intent again. The open() method can only be called in response to a user action (like a button click). First, the API doesn't actually let the eyedropper mode start without user intent. To address this concern, the API specification requires the following measures: What if a malicious website could start seeing pixels from your screen? # Privacy and security considerationsīehind this seemingly simple web API hides a potentially harmful privacy and security concern. Hit the Play button and in a limited amount of time, attempt to sample a color from the list at the bottom that matches the colored square at the top. #Eye dropper color picker windows#

# How to use the EyeDropper API # Browser support The EyeDropper API fills this gap by providing a way to sample colors from the screen. Going with this option also means other browsers would not have access to the feature. However, using this means your app would have to customize it with CSS, and wrap it in a bit of JavaScript to make it available to other parts of your app.
On Chromium-based browsers running on desktop devices, it provides a helpful eyedropper in the color picker drop down.
There isn't a browser-supplied eyedropper tool that web apps can use for their own needs.
However, doing this on the web is hard, if possible at all, especially if you want to sample colors from the entire device's screen (for example, from a different application) and not just from the current browser tab. If you're building a creative application with web technologies, you might want to provide a similar feature to your users.

Even Chromium DevTools has an eyedropper you can use when editing colors in the CSS styles panel so you don't have to remember or copy the color code from somewhere else. PowerPoint also has an eyedropper tool, useful when setting the outline or fill color of a shape. Photoshop, for example, lets users sample colors from the canvas so they don't have to guess a color and risk getting it wrong. Many creative applications allow users to pick colors from parts of the app window or even from the entire screen, typically using an eyedropper metaphor.
