This extension pulls colors from the current web page and lets you make a ColourLovers.com palette from them.
After installing the extension, load a new page or reload a page you already had open. Then click the color swatch icon. A popup will appear with up to five colors in it, pulled from the page. Click the Create Palette button to create a new palette on ColourLovers.com with the colors. If any colors from the page are already named on ColourLovers.com, their names will appear in the popup when click the color swatch icon. You can click on a named color to view that color's details on ColourLovers.com.
