ahh, ok ya ive seen them online before. Well i'd say part of it is personal opinion, everyone likes something a little different. That being said i could maybe give you a direction to head, but obviously in the end it's your choice in what you want. are your windows tinted? doesn't make a huge difference, but it may change the look depending on what color you get. also is this more of the silver white gold? or the creme white gold? (only reason i ask is cause ive seen people kinda mix the two) im assuming silvery color, but just to make sure...
if it's silver like white gold then.
Black: always looks good especially if you have black rims, black head lights (like around the light reflecting piece), the chrome window trim wrapped, or tinted windows. don't need all of it but one or two of those things help bring the color out.
if it's on the white side of that white gold spectrum id say that gold would still work, and could look nice especially with gold rims. but if you don't think youd like the look then pick something else.
Light blue: last car was blue, so assuming you like that color...
id say as long as you have some same/similar accents it will look nice. could probably have it be the only piece, but trims like that always look better if they compliment something else on the car.
you have a nice color car for adding cosmetics. white gold is a good color you can add too, and it's hard to go wrong. a lot of colors will go with white, so part of it is up to you, and what you like. Adding a few other things to the car always helps tho like matching rims, or tire nozzle caps that match the vinyl, wrapping certain parts of the car, ect. you can also get creative and do interior stuff if you really like to help bring it all together.
Idk if that helps, but hopefully i did a little.
