Eyedroppers are the design term given to those apps or features within them which allow you to select any colour on your screen and reproduce it exactly. Although it should come as standard with any serious paint or graphics app, it sometimes doesn’t in which case the only solution is to use a third party app to complement your design software.
If you’re looking for something that gives you maximum control over eyedropping then Eyedropper not only lets you pick any pixel colour on your screen but can even measure the distance between pixels and show the exact pixel coordinates. If you don’t need something quite so fancy and just want something simple, then Instant Eyedropper allows you to cut and paste pixels to your clipboard for use in other applications.
If you’re a web designer, then you’ll need something that can output the colour codes in different hex formats. ColorCop is your best bet for this task allowing you to output into HTML, Delphi, Powerbuilder, Visual Basic and Visual C++. If you prefer an eyedropper that’s easy to access from your browser, then ColorZilla is an excellent color picker and pixel zoomer that integrates into Firefox’s file menu. Finally, web designers will also find a simple but functional eyedropper in Webmaster’s Toolkit.
