Well, I started playing at my vanity and discovered I already had two colors to complete this look in my stash:
I already had MAC aqua but found dupes for the other two in the Coastal Scents 88 shimmer eyeshadow palette (of course these aren't matte). The closest to Atlantic Blue is the bottom row and second from the left. Winkle's dupe is the second row (below the row that's cut off) and third from the left. This was a really fun look and I think I should do more bright eye looks in the future.
Atlantic Blue on the left and Winkle on the right (the dupes!).
Lots of fun!
