Gothic Arch vs Form
Where Gothic Arch belongs to Benjamin Moore's range, Form is a Jotun color. These are both greige-greys, so the question isn't which hue to choose — it's where within greige-grey to land. They have nearly identical light reflectance values (31 vs 30), so they'll read as similarly Medium in most lighting conditions. Gothic Arch runs red while Form is decidedly warm, which means they'll respond very differently to warm vs cool light sources. At ΔE 0.8, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Gothic Arch vs Form in Real Spaces
1 real room side by side. Gothic Arch and Form 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 two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.

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.
