Vibrant gems and accessories in sunny yellow and orange, or luminous, swimming-pool blues can brighten up your wedding-day look.

Pantone has named turquoise its 2010 Color of the Year, and fortunately, turquoise-hued jewelry options abound at every price point. Try this beaded cluster necklace as a "something blue" with a tropical twist (or save it for the honeymoon). $16, shopthelook.net
