Hourglass Luminous Light Ambient Lighting Powder ($45.00 for 0.35 oz.) is described as a “champagne pearl.” It’s a light peach with a white shimmer but really goes on mostly colorless on the skin. This shade is designed to “create a soft, incandescent candlelight glow.” It seemed just slightly brightening but added a fine sheen all-over the skin. When blended, I did not see any shimmer particles actually on the skin, though swatched heavily on the arm or hand will show some–but these seem to really blend and sheer out. The effect is, indeed, luminous. I would describe it as a step above glowy or a sheen, because I think the effect is a bit more obvious as a result of the sheen of the powder overall.
