As referenced in the photo I used in the review for Paranoid 24/7 lip pencil, Heavy has a shimmer to it. UD calls it "shimmering nude." I am really appreciating more subdued colors these days. I really love the shimmer in Heavy and Wicked. They are the only two UD 24/7 lip pencils with a shimmer. Heavy is a rich, deep, true brown nude and the shimmer quality makes it very unique. If Urban Decay ever discontinues this product line, I will need psychotherapy.
