Heavy, Black and Pendulous is described as a "grayish blue with pearl [with a Frost finish]." It's a muted, medium-dark blue with a gray cast and frosted finish. It had nice color payoff, and the texture was soft, slightly buttery, and very blendable on the skin. I was able to get eight and a half hours of wear out of this shade. theBalm Pipeline (LE, $16.00) is brighter, more shimmery. Make Up For Ever I112 Chrome (P, $21.00) is lighter. Divergent Erudite Sapphire (LE) is similar. Makeup Geek Ocean Breeze (P, $5.99) is warmer. Makeup Geek Nautica (P, $5.99) is similar. Chanel Apparition (LE, $36.00) is a cream product, darker.
