Pearl Gray vs Opaline
Where Pearl Gray belongs to Benjamin Moore's range, Opaline is a Sherwin-Williams color. These are both green-greys, so the question isn't which hue to choose — it's where within green-grey to land. They have nearly identical light reflectance values (74 vs 73), so they'll read as similarly Light in most lighting conditions. Pearl Gray runs green while Opaline is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. At ΔE 0.9, 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.
Pearl Gray vs Opaline in Real Spaces
1 real room side by side. Pearl Gray and Opaline 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.
Bathroom
Bathrooms are one of the few spaces where you're genuinely enclosed by the paint color, which makes the choice between these two more consequential. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.

Pearl Gray vs Opaline Simulated Comparison
5 simulated room previews — drag the slider on each to see Pearl Gray on one side and Opaline 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.
