ILNP Greatness (H) is a very warm-toned, medium-dark duochrome with a metallic finish. It is a permanent nail lacquer that retails for $12.50 and contains 0.4 oz.
ILNP Greatness (H) Holographic Ultra Chrome Nail Polish ($12.50 for 0.4 oz.) has a black base with an intense, multichromatic shift that went between burgundy, warm red, copper, olive, and rich gold paired with a fine, metallic finish that had holographic micro-flakes dispersed throughout. The shift was very strong and noticeable in person without having to resort to extreme, contorted positions--no hunting for the shift required! I was even able to see that olive-green edge come through at a glance.
The texture was smooth, fluid, and not too thick or too thin, which made it easier to apply the polish in even layers that didn't pool along the edges of my nails. It seemed to self-level quite well and very few brush strokes came through, certainly not in person.
Per the brand, it has its maximum coverage in two to three coats. In the swatches, I've applied two coats and then one layer of Zoya Armor top coat (though I added Zoya Anchor as a base coat when I tested for longevity), which was plenty for full opacity. I wore this shade for 10 days and had minor tip wear and no chips.
As a FYI, the brand offers this shade with and without holographic micro-flakes--shades designated with "(H") include the holographic micro-flakes.
