Petra and Jana are both from the Zoya Fall Smoke collection. I'm combining them into one post because they are both in the grey/purple/taupe family and wanted to let you see them close to each other.
With both polishes I used a base of China Glaze Strong Adhesion, 2 coats of polish, and a top coat of Barielle Manicure Extender. Application and formula are what you expect from Zoya, smooth and not too thick or thin.
Petra is the darker of the two colors. She looks very purple in the bottle, but once dry she is a few shades darker and more grey.
Jana is obviously lighter in the bottle, but again dries a tad darker and greyer. On the nail Jana is right on the line of grey/purple and taupe. It really depends on the light which way she falls.
Both Petra and Jana are lovely, smooth cremes and fairly neutral so should be office appropriate for most places.
