Coastal Fog vs Sag Harbor Gray
Both from Benjamin Moore's palette. These are both beige-greiges, so the question isn't which hue to choose — it's where within beige-greige to land. Coastal Fog (LRV 53) reflects noticeably more light than Sag Harbor Gray (LRV 42), a difference of 11 points that becomes especially apparent in rooms with limited natural light. Coastal Fog runs yellow while Sag Harbor Gray is decidedly red, which means they'll respond very differently to warm vs cool light sources. The ΔE 8.5 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Coastal Fog vs Sag Harbor Gray in Real Spaces
2 real rooms side by side. Coastal Fog and Sag Harbor Gray are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
Living Room
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. The LRV gap is large enough that Coastal Fog will make the room feel meaningfully brighter than Sag Harbor Gray would.
House
Seen across an entire facade, subtle tonal differences become pronounced. What reads as nearly the same on a chip often reads as clearly different at scale. Coastal Fog reflects noticeably more light off the walls, making the space read more open than Sag Harbor Gray.

Coastal Fog vs Sag Harbor Gray Simulated Comparison
5 simulated room previews — drag the slider on each to see Coastal Fog on one side and Sag Harbor Gray on the other.
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.
