Imperial Gray vs Light Blue
Where Imperial Gray belongs to Benjamin Moore's range, Light Blue is a Farrow & Ball color. Hue-wise, Imperial Gray belongs to the green-grey family and Light Blue to the blue-green family. They have nearly identical light reflectance values (47 vs 49), so they'll read as similarly Medium in most lighting conditions. Imperial Gray runs green while Light Blue is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. At ΔE 2.4, 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.
Imperial Gray vs Light Blue in Real Spaces
1 real room side by side. Imperial Gray and Light Blue 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
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.

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