MAC Sweet Sovereign is a very warm-toned, medium-dark beige with a frost finish. It is a limited edition eyeshadow that retails for $17.00 and contains 0.05 oz.
Sweet Sovereign is described as a "frosty gold champagne [with a Lustre finish]." It's a light, golden beige with a frosted, metallic finish. It had decent pigmentation that went on fairly smoothly--it was buildable, at least--and performed better on the lid than the swatch suggested it would.

These saturated shadows in neutral and metallic shades and multiple finishes stay on all day long with non-creasing, eight-hour wear. The result: potent colour payoff that applies evenly, blends well and can be used wet or dry.
