S 4010-G10Y vs Cement grey in Real Spaces
2 real rooms side by side. S 4010-G10Y and Cement grey 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.
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. S 4010-G10Y reads slightly lighter here — a subtle but real difference in how open the space feels.
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. S 4010-G10Y has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

5 simulated room previews — drag the slider on each to see S 4010-G10Y 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.
