The difference is more evident in the pan than how the arm swatches depicted. These shades are very close but they are different. They are both very richly pigmented. I find Damask has a bit more of an apricot tone to it. I would say if you end up getting the Silk Road Kaleidoscope when it is released there would be no need to invest in Nutmeg in the future. If though you already have Nutmeg in your collection I don't think it should hold you back from getting the beautiful Silk Road Kaleidoscope from the upcoming Fall/Winter 2011 collection.
