Outer Sphere vs Cement grey
Outer Sphere (Benjamin Moore) and Cement grey (RAL Classic) come from different manufacturers. Outer Sphere reads as green, while Cement grey reads as grey — two distinct hue families, not close cousins. The 50-point LRV gap — 74 for Outer Sphere vs 24 for Cement grey — means Outer Sphere will open up a space more effectively. A ΔE of 37.4 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

Outer Sphere vs Cement grey Simulated Comparison
5 simulated room previews — drag the slider on each to see Outer Sphere on one side and Cement grey 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.
