To change a color in the Palette, right and choose Edit click to reveal a screen similar to the following. If the yarn did not come from the database, it will not have a name. You'll notice that a system generated name appears when you hover over the color in the palette, even though it has no name. When right clicking on the color, as shown with the orange color below, you can fill in the color name and optionally assign an name for the yarn line and yards per pound. You can also change the color by either typing the RGB value or clicking the icon to the right.
