Gentle Gray vs Mt. Rainier Gray
Gentle Gray and Mt. Rainier Gray come from the same Benjamin Moore collection. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. Their light reflectance values are nearly the same — 57 vs 59 — so neither will read significantly brighter or darker than the other. Both share a blue character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 2.0 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Gentle Gray vs Mt. Rainier Gray in Real Spaces
1 real room side by side. Gentle Gray and Mt. Rainier Gray 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.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.

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.
