I would recommend a soft brown matte or shimmer shade. You can never go wrong with a brown shadow for blue eyes!

It sounds like my coloring is very similar to yours. My go-to eye shadow is Benefit Cosmetics Creaseless Cream Shadow in Birthday Suit. It adds the right amount of brightness, while giving you a finished look. The best part- you don't need a brush. Just use your finger to tap and blend the shadow across your lid. Because of it's long wearing formula, it will stay put all day without creasing. Add liner and mascara for a bigger impact.
