MAC Savant is a very warm-toned, light green with a satin finish. It is a limited edition eyeshadow that retails for $17.00 and contains 0.05 oz.
Savant is described as a "mid-tone mustard lime [with a Satin finish]." It's a medium-dark, dirty olive green--it really is like mustard and lime together--with a mostly matte finish. It was really velvety with a smooth, soft texture that blended well but still adhered well with good color payoff to bare skin, which was a happy surprise. It wore well for eight hours on me. I couldn't think of any really great dupes for this shade, because it's darker and not a brighter, more typical chartreuse-like green. See comparison swatches / view dupes.
