5 real rooms side by side. Seeing Blue Square 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
Living rooms test a color across a full range of conditions — morning sun, afternoon shade, and evening lamp light all shift how both of these read. Cement grey has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Bedroom
Bedroom walls are often seen under warm artificial light, a context that shifts both colors from how they look on a chip. The brightness difference is modest but present — Cement grey gives the walls a little more lift.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The brightness difference is modest but present — Cement grey gives the walls a little more lift.
House
At full exterior scale, the difference between these two colors becomes much easier to judge than from a small chip. The brightness difference is modest but present — Cement grey gives the walls a little more lift.
