I've really been enjoying the Zoya color lock system lately. I love how well this stuff works with Zoya polishes, which I had always found to be incredibly streaky and difficult to work with. I am hence now rediscovering my unloved Zoya polishes. Zoya Nikki is the one I've got on at the moment.
I really like this color. It has that greyish lavener quality of Sephora by OPI's Call Your Mother, and even slightly reminds me of Metro Chic. But Nikki is much paler and therefore great for summer. I am especially enjoying it since my nails have been very bright of late. This one also has very fine green shimmer in it, which is very subtle in daylight but gives and intersting hue to your manicure in certain lighting conditions.
This is a neutral with a twist, so it's great for everyday and pretty work friendly.
