Umbra grey vs Black Fox in Real Spaces
5 real rooms side by side. Umbra grey and Black Fox 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. Umbra grey has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Kitchen
Kitchen lighting tends to be bright and directional, which sharpens contrast and makes undertone differences more apparent. The brightness difference is modest but present — Umbra grey gives the walls a little more lift.
