Zoya Blu Nail Lacquer ($8.00 for 0.50 fl. oz.) is described as a "lucky hyacinth blue cream." It's a pale sky blue with a cream finish. There's a real softness to the color, and there's also an almost indigo-tint that makes it less overtly blue. NARS Kutki is bluer, slightly darker. Cult Nails Princess is much, much darker and has shimmer, but the tone of the blue is similar. Chanel Coco Blue is much darker. Chanel Riva is more aqua.
