It's your day so you need to wear what you love. If there's any detail on your dress though, it can look amazing to complement this with your jewellery and other accessories, some might have silver or pearl embellishments for example. A lot of brides like to keep their wedding jewellery the same colour as their wedding and engagement rings, but equally many others who have white gold or platinum rings, have an overall theme for the day of rose gold, so they've worn that instead. It's your day, so as long as you love everything that you're wearing and it makes you feel fabulous that's all that matters.
