Metropolis vs Thundercloud Gray paint color comparison

Metropolis vs Thundercloud Gray

Both from Benjamin Moore's palette. Metropolis reads as grey, while Thundercloud Gray reads as blue-grey — two distinct hue families, not close cousins. Thundercloud Gray (LRV 50) reflects noticeably more light than Metropolis (LRV 24), a difference of 26 points that becomes especially apparent in rooms with limited natural light. Metropolis runs neutral while Thundercloud Gray is decidedly blue, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 22.2, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
