MAC Silver Spoon is a very cool-toned, dark gray with a metallic finish. It is a limited edition lipstick that retails for $21.00 and contains 0.17 oz.
MAC Silver Spoon Retro Matte Liquid Lipcolour Metallic ($21.00 for 0.17 oz.) is a deep gray with a cooler, almost purplish undertone and a fine, metallic shimmer over a matte finish. It had medium coverage, and it did not apply evenly at all on me. The formula dried down fully within 30 seconds, and it could take a second layer without getting too wrinkled or thick but seemed to make it more prone to flaking a bit away from the center of the lips while it wore (when it didn't do that with just a single layer). On its own (just one layer), it lasted well for six and a half hours on me and was non-drying.
