Essie's Spring Collection, A French Affair, included several beautiful pastels, and also this beautiful periwinkle blue with a hint of silver shimmer called Coat Azure. I'm not usually a blue nailpolish girl, but this one definitely converted me.
This is a medium blue. Just the slightest shimmer - it really takes the right lighting (i.e. natural light below) to capture it. The formula is great - very smooth and easily applied. Below is two coats.
The color reminds me of spring, specifically the little vinca vines or myrtle that pop up around here in my garden - beautiful!
