Bossa Blue is described as a “royal blue with brown pearl.” It’s a warm-toned taupe–a grayish brown with a gray sheen. The texture was a bit dry and powdery, and the resulting payoff when applied dry was semi-sheer, while when applied damp, it was more semi-opaque. I found it fairly buildable on the lid, but it does need some layering. There’s no shortage of shades like this, even with MAC’s releases. MAC Pastelluxe #5 is warmer. Disney Midnight Hour #4 is darker. Urban Decay Mushroom is a cream product but similar in color. Urban Decay Armor is a touch darker. Urban Decay Mushroom is similar. NARS Grand Palais #1 is lighter. MAC Keep Your Cool is darker. MAC Twilight Falls is browner. Giorgio Armani #4 is more shimmery. See comparison swatches.
