I have always love White Gold as My original badge is white gold with Saphires but the one I wear now is White Gold and Pearls in the Creseant and 3 Shaphires with 8 Diamonds.
But, I do love the Yellow gold with Pearls in Creseant and 3 Rubys and 8 Opals.
Oh, both have Guards in correct colors so I do not lose either one.
Get Guards when available!
