This is not the best picture, but hopefully it will be helpful. These are all the teal shadows that I own on NW15 skin.
Top Row (L-R): Brill, Surreal, Zonk Bleu!, Electric Eel, Plumage
Bottom Row (L-R): Steamy,
Moonflower, Meadowland, Pompous Blue, Blue Edge
On me, Moonflower is VERY similar to Zonk Bleu!
Again, NW15 wearing Petalpoint, Fertile and Orchidazzle:
