Tranquil is described as a "soft stone." It's a light, gray-leaning taupe with a satin sheen. It had decent color payoff, but it was sheerer than the other shades. The texture was soft without being powdery, while the color lasted for nine and a half hours on me. Dior Rivage #2 (LE) is cooler-toned. Tom Ford Beauty Ice Queen #3 (P) is cooler-toned.
