Janet Perry at Nuts About Needlepoint found another cool widget and, of course, has come up with a needlework application for it. Input an image or URL into pic2color, and the tool generates a palette of swatches of the colors used in the image. For Janet’s ideas about how to use the tool with needlework, see her blog post. To get the widget, go to the pic2color page at widgetbox.com.
Palette Generator is a tad bit easier to use:
