Eyedropper is a useful little program which I couldn’t be without. It will tell you the hex, RGB or CMYK of any colour on screen if you hover your cursor over it, and so is invaluable for web development. Many people use Colorzilla for this, which is a Firefox plugin. However, the advantage of Eyedropper is that it works anywhere on screen, not just inside the browser window.
In addition, it also gives you the x and y mouse coordinates, which is very useful for checking that things line up properly. The program is very small and unobtrusive, it sits in the systray until you double-click the icon to pick it up. Then it will follow your cursor around, until you double-click its icon in the systray again to put it back. (more…)
