Gray Cloud vs Blue Iris
Where Gray Cloud belongs to Benjamin Moore's range, Blue Iris is a Sherwin-Williams color. Both sit in the blue-grey family, which is useful context if you're narrowing within a single hue direction. Blue Iris (LRV 73) reflects noticeably more light than Gray Cloud (LRV 70), a difference of 3 points that becomes especially apparent in rooms with limited natural light. Gray Cloud runs blue while Blue Iris is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. At ΔE 1.4, 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.
Gray Cloud vs Blue Iris in Real Spaces
1 real room side by side. Gray Cloud and Blue Iris 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. Blue Iris reads slightly lighter here — a subtle but real difference in how open the space feels.

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.
