Thunder vs Tranquil Dawn in Real Spaces
6 real rooms side by side. Thunder and Tranquil Dawn 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. Tranquil Dawn 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 — Tranquil Dawn gives the walls a little more lift.
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 — Tranquil Dawn 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 — Tranquil Dawn gives the walls a little more lift.
