Forbidden is a cool-toned, gray-tinged, medium-dark plum with a satin-matte finish. It had a soft texture, and the resulting pigmentation was fairly good–it was also buildable to fully opaque color in two to three layers. MAC Bruised Sky (LE, $15.00) is cooler-toned. Benefit Rain Check (P, $20.00) is slightlyh purpler. Inglot #358 (P, $6.00) is very similar. See comparison swatches.
