I'm sure it's been thought of a gorillion times, but having several tens of individual variants for 1 specific cosmetic/accessory that usually has 1 or 2 general areas with unpreferable colors is rather disappointing personally.
I've been messing around with model viewer, and thought "wouldnt it be great if I could just take the heavy owlite robe for example and change it's arm color into a divine variant".
Having a singular variant of a cosmetic obtainable from a box, just with the ability to pay a price to have 3 separate pieces of it paintable into whatever available combination of colors sounds like a solid system in my head.
Sort of like you pay a price to change your personal color, eyes or height, but for cosmetics.
Just putting this out there, this just wouldnt leave my head.
If anyone reads this, hi lol.
