KVD Beauty Nietzsche is a very cool-toned, light-medium blue with a matte finish. It is a permanent eyeliner that retails for $19.00 and contains 0.019 oz.
Kat Von D Nietzsche Ink Liner ($19.00 for 0.019 fl. oz.) is described as a "periwinkle." It's a brightened, cornflower blue that leans purple with a mostly matte finish. It had semi-opaque color coverage when applied, and it was sort of buildable, but it was difficult to get the coverage to be even if you used more than one stroke. It lasted for sixteen hours with a couple of flaked off pieces (hardly noticeable). MAC Royal Wink (LE, $16.00) is darker. NARS Most Wanted (LE, $24.00) is darker.
