MAC Cast Iron Technakohl Liner ($16.00 for 0.012 oz.) is described as a "elephant grey." It's a muted, bluish-gray with a satin finish. It was waxy and sheer, though I was able to build it up to semi-opaque color coverage with several passes. It wore well for seven hours before it faded. At least this shade was more unique, though the formula is still disappointing. See comparison swatches / view dupes.
