Hi! Ok, so I had a lot of help from a lot of different lists and websites. I want you to know that I don't have this palette, so I can't say for sure if these colors are similar. I'm just going by word of "mouth" or word I guess?!
I describe each shadow and say what the dupe is. If it is a Mac shadow I try to say a dupe for that.
I already have lists of dupes, and I didn't keep track of where I got those from. Just from all over the internet basically. So I used the lists I already had, and here are some other websites that helped me:
http://mupnorth.blogspot.com/2011/12/urban-decay-naked-2-palette-mac-dupes.html she lists the palette 2 Mac dupes,
http://www.temptalia.com/urban-decay-naked-1-vs-naked-2-palette-dupes-comparison-swatches she compared the first palette with the second one and also described the colors, and
http://inexpensivebeauty.weebly.com/drugstore-and-etailer-dupes.html and this person listed dupes for Mac.
http://www.temptalia.com/urban-decay-naked-2-palette-swatches-photos-reviews for her descriptions of the Urban Decay Palette 2 shades. Diva Makeup Queen has found her own dupes this is a link to part 1
