GP01 Hologram is not really a nail color itself, but as the name "nail lacquer glitter" suggest rather a glitter topcoat - a clear nail color with tiny shimmering glitter particles. Most of them are silver, but some glitter in all colors of the rainbow. It looks really neat in the bottle. My problem with these kind of nail glitters is that it always looks so neat in the bottle, but then, when you put it on your nails, you hardly see anything at all. A few lonely glitter particles and that's all. With some of them you can still get an effect similar to what it looks like in the bottle by applying 2 or 3 layers. The Etude House Lucid Darling Nails Crystal Gold nail color for example is one where 3 layers give you amazingly sparkling nails. However, the TonyMoly Nail Lacquer Glitter #GP01 Hologram still looks a bit meager with 3 layers.
This one doesn't really look very good on bare nails, just on top of another nail color. Sadly I don't really seem to have many nail colors that go well with it, because most of my nail colors are pink-, lavender- or beige-shaded and I do not think it matches well. This would probably look best on a gray or black nail color. I am not as fond of the TonyMoly Nail Lacquer Glitter as I thought I would be.
