My favorite is blue which I do believe I've highly stated that before; I just can't help it! When I'm strolling through my drawers full of nail polish for some reason I usually gravitate towards the blues, purples, and pinks. This time I reached for China Glaze "So Blue Without You" since as I grabbed it I noticed that it's been quite a long while since I've used this one. It's a blue that is bright, yes, but I also like that it has a little shimmer quality to it. It reminds me of a sky blue with some metallic/shimmer thrown in there to make it different from a regular sky blue color.
