Rockport Gray vs Perennial Grey
Rockport Gray (Benjamin Moore) and Perennial Grey (Little Greene) 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 — 37 vs 38 — so neither will read significantly brighter or darker than the other. Both share a red character, which means they'll respond to light and surrounding materials in similar ways. ΔE 3.6 means they're clearly different, but not dramatically so — they'd pair well in the same room.

Rockport Gray vs Perennial Grey in Real Spaces
1 real room side by side. Rockport Gray and Perennial 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.

5 simulated room previews — drag the slider on each to see Rockport Gray on one side and Perennial Grey 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.
