Why can't I control the border color for other materials than vinyl?Updated 5 months ago

The reason you can't control the border color for materials other than vinyl is that each material has its own inherent color, attributes, and specifications—such as holographic or glitter finishes. Applying additional colors to these materials would override or remove their unique characteristics. 

As a result, the option to control border color is only applicable to vinyl, allowing you to customize your designs while preserving the special features of other materials. This ensures that the distinct qualities of each material remain intact!
