Color Editor - New Named Color Button
Clicking this button opens the New Named Color dialog box. The new color is applied to the selected objects, so if you just wish to create a new color and not use it, make sure there are no objects selected. For more details on creating named colors, see Creating named colors. If you click this button whilst holding down keys, you can skip past the dialog box and specify what you want to do more quickly:
Shift Create a copy of the current color.
CTRL Create a shade of the current color.
Shift+CTRL Use the current settings in the New Named Color dialog box.
