This post is about a Firefox Add-on called ColorZilla, a single add-on which is combined of Advanced Eyedropper, ColorPicker, Page Zoomer and other colorful goodies!
With ColorZilla you can get a color reading from any point in your browser, quickly adjust this color and paste it into another program. You can Zoom the page you are viewing and measure distances between any two points on the page. The built-in palette browser allows choosing colors from pre-defined color sets and saving the most used colors in custom palettes. DOM spying features allow getting various information about DOM elements quickly and easily!
If you are a blogger or webmaster, this Add-on will be very useful to you. For instance, you visit a website/blog and liked the colors they used in links or menu-bars, then you can just click ColorZilla(at the bottom left of the browser) and move the cursor to that color. You will get the color codes which you can use in your blog’s template to change the layout colors!
