ColorZilla - ColorPicker Eyedropper Page Zoomer

Recently I posted an article on How to measure the pixels on screen, while you are online in a web browser. Now here's another helpful tool, for webmasters.
Many times, while adding any widget, button or simply placing ads on your websites, you would have faced the problem of not knowing the exact HTML color code of the background, or other widgets already placed over there. And just by looking at the color it is not possible to tell, exactly which shade of gray, blue, red or green is present on screen.

So if you are using Firefox, then here is an add-on for your web browser [ColorZilla.Mozilla], which makes the whole work a lot simpler. Just click on tool - ColoZilla, present on your browser's taskbar, and hover the cursor on any part of the browser or web page to get the HTML value of every single pixel separately.
It mainly has the following features:
* Eyedropper - get the color of any pixel in the browser window
* Color Picker similar to ones found in Photoshop and Paint Shop Pro
* Palette Viewer and editor
* Webpage Color Analyzer
In its Menu's screen shot you can see many more features too:
