Pearl River #1 is a pale, warm white with a frosted finish. It had decent color payoff, but it was on the sheer side. It was buildable, but it wasn’t densely pigmented. The texture was incredibly soft and finely-milled, though; one of the softest textures I’ve seen from Chanel. There is no shortage of frosted, white eyeshadow, so it’s highly likely that you have something similar in your stash. Giorgio Armani Open is not as warm-toned. Tarte Macaroon is similar but even less pigmented. bareMinerals Silhouette is more pearl-like in finish. Guerlain Terra Azzurra #1 is also similar.
