MAC Havana is a moderately warm-toned, medium-dark brown with a pearl finish. It is a permanent eyeshadow that retails for $20.00 and contains 0.04 oz.
MAC Havana Extra Dimension Eyeshadow ($20.00 for 0.04 oz.) is described as a "dirty copper brown." It's a dark brown with warm, yellowed undertones and a frosted, lightly metallic, finish. It had semi-opaque pigmentation dry, but the color was noticeable lighter, whereas damp application was deeper and fully opaque. It wore well for six hours dry, eight hours damp. The new version has less pigmentation dry than it used to, though it is more in line with how the formula is described now. See comparison swatches / compare dupes side-by-side.
