Blackheart is a deep, dark purpled black with burgundy sparkle. It had so-so color payoff in a single stroke, but it is buildable to more opaque color in two to three layers. It wore well for eight hours on me with slight thinning apparent after nine hours. MAC Strong Willed (P, $20.00) is lighter. MAC Dark Diversion (LE, $16.00) has no sparkle.Bobbi Brown Black Plum (P, $24.00) is lighter, less sparkle.See comparison swatches.
