Instant Eyedropper is other one of those applications which let you know the value of any colour just placing the mouse over it.
You only have to choose the format you want it to be converted: HTML, Hex, VB Hex, Delphi Hex and RGB. If you choose the HTML format, you will be able to know it in 4 different formats.
Instant Eyedropper s run in the system tray bar and if you want to use it, you only have to click it and then place the mouse over the colour you want to know the value.
The mouse cursor will be transformed into a magnifier glass which lets you select pixel areas of 3×3, 5×5, 7×7 and 9×9. Once you select the colour, its value will be automatically copied, so you will only have to paste wherever you need.
