Black grey vs Shiitake in Real Spaces
4 real rooms side by side. Seeing Black grey and Shiitake 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. Shiitake reflects noticeably more light off the walls, making the space read more open than Black grey.
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. Shiitake 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. Shiitake reflects noticeably more light off the walls, making the space read more open than Black grey.
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. Shiitake returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

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