Ecommerce Storefront
The variant a customer chose has to survive the cart, the order and the return — and usually it does not.
Catalogue, product pages with real variants, the shade and size decision, cart, checkout, and the order record that carries the chosen variant by identifier rather than by name.
The brand can finally see which shades sell.
It is a storefront, not a marketplace listings service, and it does not formulate or register products.
