Cathedral Gray vs Treron
Cathedral Gray (Benjamin Moore) and Treron (Farrow & Ball) come from different manufacturers. These are both greige-greys, so the question isn't which hue to choose — it's where within greige-grey to land. Their light reflectance values are nearly the same — 26 vs 25 — so neither will read significantly brighter or darker than the other. Where Cathedral Gray leans red, Treron reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. ΔE 4.4 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Cathedral Gray vs Treron in Real Spaces
2 real rooms side by side. Cathedral 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
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. The distinction reads clearly at room scale, making the choice between them concrete.
Dining Room
Dining rooms often rely on warm incandescent or candlelight, which flatters warm undertones and mutes cool ones. Side by side like this, the difference is easy to read — which is exactly why seeing them in a real space is more useful than comparing chips.

5 simulated room previews — drag the slider on each to see Cathedral 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.
