I have not used the white and gold vein before. Never had a call to, but I could it is really no different than any other vein.
There are loads of things I can do that you cant do with anodizing. Textures, veins, metallics, color changing flakes, holographic flakes, true whites, true blacks, etc.
I am currently working on a wrinkle black dsp v2 now with a chameleon flake in it.
