Barry M blueberry is a standard pastel blue polish, nothing too special in all honesty. Unlike the lilac version, this was opaque in two coats, however I still did my three coats for y peace of mind XD
Having got quite a collection of Gellys now, I do recommend them for their range of colours as some aren't duped in the normal Barry m collection (keylime, for example. The normal Barry m lime colour is a sheer jelly) and they are pretty opaque in two coats. However they aren't as shiny as they are with a coat of Seche Vite on too, but I think very few topcoats/gel polishes can compare to Seche Vite!
