I'm stylizing a brand name and while one sounds better, I don't quite know if it'd be acceptable in a traditional sense.
The name I like is Tequila Viernes. This should be Friday Tequila, which is what I want. I don't understand whether Viernes classifies as an adjective noun or an adjective. The example I saw on here was "gato grande" or "big cat". Big and Friday to me are essentially the same, nebulous ideas without a physical form, but one is formal.
Would that make my usage justifiable or would native speakers have a problem with it? Tequila de Viernes does not flow as well as Tequila Viernes, so for a brand it's a tough line to walk.
