Copley Gray vs Treron
Copley Gray is a Benjamin Moore color while Treron comes from Farrow & Ball. Both sit in the greige-grey family, which is useful context if you're narrowing within a single hue direction. With LRVs of 26 and 25, they'll behave almost identically in terms of how much light they reflect back into a room. The tonal difference — Copley Gray's red character against Treron's warm — becomes most visible against white trim or in morning light. With a ΔE of 2.6, the difference is subtle — you'd need them side by side to reliably tell them apart. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Copley Gray vs Treron in Real Spaces
4 real rooms side by side. Copley Gray and Treron 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
Living rooms test a color across a full range of conditions — morning sun, afternoon shade, and evening lamp light all shift how both of these read. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.
House
At full exterior scale, the difference between these two colors becomes much easier to judge than from a small chip. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.
Kitchen Cabinets
On cabinetry, undertone and temperature become more pronounced against countertops and hardware. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.

5 simulated room previews — drag the slider on each to see Copley Gray on one side and Treron 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.
