MAC Serenade is a slightly warm-toned, light plum with a frost finish. It is a limited edition eyeshadow that retails for $17.00 and contains 0.05 oz.
Serenade is described as a "mid-tone orchid pink with blue duochrome pearl [with a Veluxe Pearl finish]." It's a warm-toned, medium pink-shimmered plum with a frosted finish. It had nice pigmentation, and the texture was fairly smooth and easy to use. On me, the color didn't show signs of fading until after eight hours of wear. MAC Violet Blend #3 (LE) is warmer. Fyrinnae Meerkat (Pressed) (P, $8.25) is darker. Milani Pink Twice (P, $6.99) is slightly darker. See comparison swatches / view dupes.
