Penthouse is deep matte black with subtle silver sparkle. It has really intense pigmentation, but it’s very blendable. I used the lightest dab of product to darken my crease when I was testing out the eyeshadows, which was plenty! If you tend to be a fiend for black eyeshadows, you probably have something similar, since it is a rather basic color (see the black eyeshadow swatch gallery). I noticed that the silver sparkles translated a bit more on the lid with this shade than they typically do (a lot of times they just get lost).
