I hesitate to post my frankens because I make them so haphazardly. As such, I hope to give you only a very loose guideline for inspiration purposes only, so don't hold your breath for exact measurements.
I say this franken is only sorta holo-y because obviously the effect is weak. Sun is required to make it look super special ...
And now for inspiration purposes only:
For Me, It Works for the name!) There are plenty of dupes though, including -
a. Essie Midnight Cami
b. Sally Hansen - Navy Baby (Salon)
c. Sally Hansen - Blazing Blue (Insta Dri) - this has some green micro stuff though
2. Color Club - Worth the Risque
