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. See swatches of all dupes / view dupes side-by-side.
