A-England Galahad: 'Mystic Vibrant Blue Green', i would describe it as more of a bright turquoise/teal blue.
Revlon Surf: Ocean Dusty Blue Crème (totally bought this because it reminded me so much of Chanel Blue Boy)
OPI Dating a Royal: ...a 'royal' jelly/crème blue
A-England Tristam: 'night blue sky with starlight glimmer and glow', an indigo holographic
Deborah Lippmann Lady Sings the Blues: 'silver sparkled blue', a midnight navy with silver and blue large hexagonal and small glitter particles. (Jelly finish)
Essie Bobbing for Baubles: 'deepest, darkest sapphire', dusty navy blue crème with grey undertones
Essie Lilacism: A satiny smooth lilac, with grey undertones (full review here)
Essie Cocktail Bling: blue/lavender toned gray
Zoya Caitlin: Also blue/lavender toned gray, but a few shades darker. Definitely in the same family as Essie Cocktail Bling.
I have too many here that i love :3 but how amazing are the A-England nail polishes? i seriously need to invest in more, they're absolutely incredible!!!
