For serious collections
You own hundreds of shades.This is where they live.
Every bottle accounted for. Every wearing logged — the date, the fingers, what sat underneath. Every shade tied to the ones it lives beside, so you never buy the same color twice.
The shelf
Every bottle: brand, finish, what it cost, where it came from, and the day it arrived.
The wear diary
Each manicure as a record — the date it went on, which finger wore what, and the layers underneath.
The pairings
Shades link to shades without limit — what you wore together, and what sits too close to something already on the shelf.
