Color Club Blue Heaven Nail Lacquer ($10.00 for 0.50 fl. oz.) is softened, lightly cool-toned baby blue with holographic shimmer. I could only think of one shade that was even remotely similar, which was Color Club Over the Moon, but it is a brighter, medium blue (it does have holographic shimmer, though). You can compare them both here.
