From Left to Right: Orly Mint Mojito, OPI Hey Get in Lime, Revlon Minted, Essie Mint Candy Apple, China Glaze Re-freshmint.
The Orly Mint Mojito is totally different than the rest, it's a bright green, not minty like the others at all. You can tell that the last three are all similar tones, pale, light pretty mint greens.
Index to Pinky: OPI HGIL, Essie MCA, China Glaze Re-freshmint and Revlon Minted.
From the swatches above you can tell that OPI HGIL is a yellow lime green, my bottle is a bit weird the yellow at the bottom doesn't really mix in right regardless of how much you shake it. Essie MCA is a pale, stark white mint with blue undertones, China Glaze Re-freshmint is more green than MCA, the Revlon Minted is similar to the China Glaze. HGIL is very sheer, requires a lot of coats 3-4, the Essie is pretty nice, my favourites out of all of these.
