Colorado Gray vs Aqua-Sphere
Where Colorado Gray belongs to Benjamin Moore's range, Aqua-Sphere 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. Colorado Gray (LRV 44) reflects noticeably more light than Aqua-Sphere (LRV 41), a difference of 3 points that becomes especially apparent in rooms with limited natural light. Colorado Gray runs blue while Aqua-Sphere is decidedly cool, which means they'll respond very differently to warm vs cool light sources. At ΔE 1.9, 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.
Colorado Gray vs Aqua-Sphere in Real Spaces
1 real room side by side. Colorado Gray and Aqua-Sphere 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.

5 simulated room previews — drag the slider on each to see Colorado Gray on one side and Aqua-Sphere 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.
