Photoshop tip to grab color anywhere on the screen
Designers can get color inspiration from anywhere, and often times it is right from the screen you are looking at. So how do we grab those colors from our screen for use in our projects that are outside of open Photoshop documents?
Use the Photoshop Eyedropper Trick
If you double-click the color selector in Photoshop and get the color picker dialog box, you can sample colors from outside that box, but only from open Photoshop documents. There is a trick you can use in Photoshop though to sample color from anywhere on the screen. Select the Eyedropper tool. Then click and hold down the mouse button inside an open Photoshop document. With the mouse button held down, you can then drag the eyedropper tool outside the Photoshop document to sample color from anywhere on the screen.
