Deep Breath vs Cement grey in Real Spaces
5 real rooms side by side. Seeing Deep Breath 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 reflects noticeably more light off the walls, making the space read more open than Deep Breath.
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 returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
House
A full exterior is the most demanding test for a paint color — scale and outdoor light both amplify differences that seem small on a swatch. Cement grey returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
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 reflects noticeably more light off the walls, making the space read more open than Deep Breath.
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 returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

5 simulated room previews — drag the slider on each to see Deep Breath 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.
