Have to chime in on Romp. I was getting bored with my usual eyeshadows and wanted some new ones. I didn't have time to get to the MAC store or counter so after some research I decided on four colors; Romp, Naked Lunch, Shale and Carbon. As I only have about 8-10 MAC shades I wanted to build my collection and thought these colors were pretty basic and had great reviews.
By far my favorite is Romp. It is a great true medium brown with gold shimmer. No orange what so ever, which I love.
I have fair skin, blue eyes and cool undertones, I am an NW15 and have similar coloring to Julianne Moore. This color is great. I love wearing Satin Taupe but it is a bit dark for me and looks harsh if I am tired, Romp is perfect. If I am tired it really brightens up my eyes, no one has told me I look tired while wearing it. I have been wearing Romp on my lids and blending it up to the crease, a couple times I used Charcoal Brown in the crease, both ways looks appropriate for daytime/office. I use TFSI followed by MAC Groundwork paint pot then Romp on top, staying power is fantastic, 12+ hours a couple days, very little fall out and color pay off is great.
I highly recommend this color and did want to mention that I think this color would be stunning on people with green eyes. My blue eyes stand out with this color but I think on green eyes it would be even better.
