There is no hard and fast rule for choosing jewelry according to your hair color. But let’s say there are some points you may want to consider. According to one expert:
If you have blonde or golden shade of hair, gold metal earrings may be more flatter to you than sterling silver. Likewise, dark haired women tend to find sterling silver and platinum to be complimentary metals for them. If you have red hair, gold is striking, but you may want to venture into copper which tends to look extraordinary on redheads. Mixed metals including earrings with combinations of gold and silver, or silver and copper tend to be flattering on almost anyone.
