Developers, graphic designers, digital artists and web-designers need to make use of a Color Picker software for identifying colors or a Ruler to measure objects on the screen. While one can always use a 3rd-party freeware like ColorPix, Pixie or Just Color Picker for identifying the colors, Internet Explorer 10 includes a Color Picker and a Ruler tool.
To access the built-in tools, you have to open Internet Explorer and press
F12 to open the
Developer Tools. A panel open in the bottom of Internet Explorer 10. These are the Developer Tools. Click on the
Tools menu item, to open its sub-menu. Here you will be able to see
Show Color Picker and
Show Ruler items.
