I've been swatching my shadows too to try to talk myself out of the new Charlotte Tilbury palette. Let us know if you are able to dupe that last shade!(A bit of a brain dump about a thing.)
So you probably know I swore off pre-made eyeshadow palettes a while back. I was just in the Bobbi Brown thread and saw Elegant's swatches of the Downtown Cool palette. It seems to be right up my alley at the moment, as I've been going through a mostly matte phase lately, and it's neutral that leans more cool.
I've gone through my eyeshadow stash to try to dupe the palette. The top left shade is pretty close to MAC Typographic. The closest thing I have to the bottom right is MAC Mystery (maybe some differences in undertone?). The bottom left is kind of similar to either MAC Copperplate or Makeup Geek Friend Zone (moreso the latter, perhaps? I vascillate between the two. I also pulled out MUG Faux Fur). I don't have anything like the top right. The downside is I did this swatching at night with not a lot of light, soooo... I think I'll try again during daylight.
