Blue Nova vs Cement grey
Blue Nova (Benjamin Moore) and Cement grey (RAL Classic) come from different manufacturers. Blue Nova reads as blue, while Cement grey reads as grey — two distinct hue families, not close cousins. The 7-point LRV gap — 24 for Cement grey vs 17 for Blue Nova — means Cement grey will open up a space more effectively. A ΔE of 31.3 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 5 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Blue Nova vs Cement grey in Real Spaces
5 real rooms side by side. Seeing Blue Nova and Cement grey in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
Living Room
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. Cement grey reads slightly lighter here — a subtle but real difference in how open the space feels.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. Cement grey has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. Cement grey has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Front Door
On a front door, the color is both the first and last thing you see — a context where even a modest tonal difference reads clearly. Cement grey reads slightly lighter here — a subtle but real difference in how open the space feels.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Cement grey has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

Blue Nova vs Cement grey Simulated Comparison
5 simulated room previews — drag the slider on each to see Blue Nova 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.
