Glam Green (18M) is a bright, light gray with cooler undertone and warmer, green-gold shimmer that gave it a metallic finish. It had opaque color coverage in one layer, which applied well to bare skin with a smooth, even lay down of color. The texture was soft, smooth, and dense without being too firmly pressed into the pan nor was it too thick. It was creamy enough to blend easily on my lid but had improved wear at eight and a half hours before fading a bit.
The current version is much, much lighter and cooler-toned; more of a green-tinged silver/gray compared to a pewter-gray (which may or may not be a good thing).
