Blue grey vs Waterloo in Real Spaces

5 real rooms side by side. Blue grey and Waterloo 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

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. Blue grey has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

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.
