Eyedropper

• Click on the ColorZilla toolbar icon
• On Windows, the eyedropper is activated automatically - go over the pixel you want to sample and click on it. On Mac and other platforms, select "Pick Colour From Page".
• The monitoring stops and the last sampled colour value is remembered.
• If the sampled colour is one of a dynamic element (like a hovered link) and you want the original colour, click on the main ColorZilla icon again and choose "Resample last location".
