Colorzilla add-on for Firefox

If you want to see the colors used in a website then Colorzilla add-on is the best solution. It shows the colors in RGB format and hex.
Just download it from here, after the installation a little eyedropper will appear at the lower-left corner of Firefox. Click on it and move your mouse there you want to find out the color. If you click you “lock” the color and deactivate the plug-in.
Really useful for web designers!
