This is actually the right answer. The way most “paints“ work is they absorb all of The colors of light except the one you see.
These “color flopping pigments” work differently. They modify a certain wavelength of light into a different wave length of light in a way that creates this cool pearlescent appearance that you like.
The problem is the light passes through the coating and reflects off of your nail, which interferes with the cool look you’re going for. You need the black undercoat to absorb the light that passes through so the only light reflected for you to see is the cool effect you you’re going for.
