The Sharp Color Picker is a full featured color picker. It allows picking colors from any web page. Its color editor window contains the ability to edit color as hex, or though its RGB or HSL values, or by name.
It also contains a selection of widgets, including a color wheel and HSL panel for visually playing with the color. The current color display, lets you easily slight variations on the shade of the color. It also has a palette of colors based on the "Browser Safe" colors as an easy starting point for mixing new colors. It also remembers your last selection of colors.
The extension is part of the Toolbar Buttons project and is built with the MozButton SDK. Follow us on Twitter, or get involved on GitHub.
