Cathedral Gray vs Gothic Arch
Cathedral Gray and Gothic Arch come from the same Benjamin Moore collection. These are both greige-greys, so the question isn't which hue to choose — it's where within greige-grey to land. The 5-point LRV gap — 31 for Gothic Arch vs 26 for Cathedral Gray — means Gothic Arch will open up a space more effectively. Both share a red character, which means they'll respond to light and surrounding materials in similar ways. ΔE 5.2 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Cathedral Gray vs Gothic Arch in Real Spaces
1 real room side by side. Cathedral Gray and Gothic Arch 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. Gothic Arch reads slightly lighter here — a subtle but real difference in how open the space feels.
