MAC Her Cocoa #4 is a moderately warm-toned, medium-dark brown with a frost finish. It is a limited edition eyeshadow that retails for $17.00 and contains 0.05 oz.
Her Cocoa #4 is described as a "chocolate bronze [with a Lustre finish]." It is a dark brown with warm, reddish undertones with gold and bronze shimmer for a frosted finish. It had good pigmentation, and it applied smoothly and evenly. This is what was listed as Mulch in my information, and at the very best, Her Cocoa #4 is a smidgen darker, and it was only noticeable under a lot of light. It wore well for just over eight hours. MAC Divine Decadence is less frosted. Urban Decay West is darker. MAC Mulch is dead-on when I swatched the two side-by-side. MAC Buckwheat is browner. See comparison swatches.
