Steal Color From Anywhere
In previous versions of Photoshop, you could click the Eyedropper tool (I) on any color within your image, and it would steal that color and make it your new Foreground color. The only drawback was you could only steal colors from within an open document window. Back in Photoshop 7.0, Adobe cut the Eyedropper tool loose from the chains that bound it, and now, as long as you click within an open image first, you can drag right out of your image window and sample a color from, well, anywhere. That includes sampling colors from other applications, Photoshop’s own Toolbox and menu bars, and even your computer’s desktop pattern. Just remember to click in your image first, and then drag that Eyedropper to a new world of color delights that dare not speak its name.
