These pictures are in natural, overcast lighting with no flash. (The weather has been wonderful here the past few days so I was able to get proper, outdoor pictures for the first time in months. I love spring!) On the nail, I have shown it here over Dr.'s Remedy "Nobel Navy". I also swatched this (but ultimately chose the navy for the "official" swatches) over "Balance Brick", "Passion Purple", and "Healing Heather Grey" (all also from Dr.'s Remedy) and I loved how it looked over all of them.

I think the whole collection looks promising. I hope to get a couple more of the colors from this collection, Evolution and In Theory especially look nice to me.
