Black vs Thames Fog
Where Black belongs to Benjamin Moore's range, Thames Fog is a Valspar color. These are both greys, so the question isn't which hue to choose — it's where within grey to land. Thames Fog (LRV 27) reflects noticeably more light than Black (LRV 5), a difference of 23 points that becomes especially apparent in rooms with limited natural light. With a ΔE of 39.9, 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.
