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

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.
