If your hair is blonde or light brown, yellow gold. If you are a dark brunette or redhead, white gold.
This depends on your overall coloring. Do you normally have cool coloring (pink/blue undertones) or warm coloring (yellow undertones)? It depends little on your hair color you can be blonde/redhead/brunette (light or dark) with cool coloring OR warm coloring. That being said, you have adjusted your skin to a warmer tone. If you normally have warm coloring (chestnut brown/caramel blonde/bright red), then yellow gold will suit you better. If you normally have cool coloring (chocolate brown/black/icy whitish blonde/ deep red), then white gold will look fine as will yellow gold. When in doubt, choose rose gold. It has an opalescent effect that tends to give it the appearance of changing color in different lights.
yellow gold without a doubt
I'm Hispanic so my skin tone is fairly tanned and white gold and yellow gold suit me. I think that they'll look good on you.
