I really like pink and grey together, and looked at a whole bunch of grey polishes online before buying Dorien Grey (that is the correct spelling on the bottle). I can't say that it was exactly the grey I was looking for as it tends to lean ever so slightly green in certain light, but it still looked pretty against the pink.
