Stonybrook vs Cement grey
Where Stonybrook belongs to Benjamin Moore's range, Cement grey is a RAL Classic color. These are both greys, so the question isn't which hue to choose — it's where within grey to land. Stonybrook (LRV 29) reflects noticeably more light than Cement grey (LRV 24), a difference of 5 points that becomes especially apparent in rooms with limited natural light. The ΔE 9.2 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Stonybrook vs Cement grey in Real Spaces
3 real rooms side by side. Stonybrook and Cement grey 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 brightness difference is modest but present — Stonybrook gives the walls a little more lift.
Bathroom
Bathrooms are one of the few spaces where you're genuinely enclosed by the paint color, which makes the choice between these two more consequential. Stonybrook reads slightly lighter here — a subtle but real difference in how open the space feels.
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. Stonybrook reads slightly lighter here — a subtle but real difference in how open the space feels.

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.
