Unfortunately no. This one is ILNP's color called Mega.
I do have one from Indigo Bananas called Rainbow ALL the things! But I'm almost out of it.
Holographic or "holo" in nail polish is just a fancy way of saying rainbow. So any sparkles that give a rainbow effect are holo. There are 2 types, linear, which gives a flare effect (which is semi-visible? I have a better pic that I can share) and scattered, which as it sounds, has little scattered rainbow glitters.
Iridescent, on the other hand is generally just a 2-3 color shift of generally very fine shimmer/glitters. Still pretty, but not holo.
