Hello, today I've decided to fix an accessory that originally should be golden (and it is when a Sim has no hair), but when hair is equipped displays the hair color. I've tried to experiment with the info I could get through GPT and Gemini and I was actually able to stop it from displaying hair color with the cost of it losing any other color and its shine (since its texture should be metallic). Could anyone help with what should i fix here? (Currently I've tried changing its type from brow piercing to necklace, changing shaders in Geometry from SimSkin to Decal and Phong through Sims 4 Studio and changing its UVMap entirely in Blender, UVMap changing had made its color to gray in-game and broke its mesh a bit)

Also I should confirm, this item wasn't made by me and I've decided to edit it for my personal need. The creator of it has stated that its allowed.
