MAC Platinum Shadow is a slightly cool-toned, very light silver with a frost finish. It is a limited edition eyeshadow that retails for $17.00 and contains 0.05 oz.
Platinum Shadow is a light, silvery pewter with neutral-to-warm undertones and a sparkling, metallic finish. It had a Lustre finish, so the medium coverage wasn't unexpected (as Lustres are sheerer), and for a Lustre, it was actually less chunky/dry compared to most. There was some fallout during application and while worn, so I would recommend using it with a dampened brush or with an adhesive base for best results. It lasted for seven hours with some fallout.
