Dolphin Fin vs Tranquil Dawn in Real Spaces
3 real rooms side by side. Dolphin Fin 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. Dolphin Fin has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Dining Room
Dining room light is typically the warmest in the house, which shifts both colors toward the red end of the spectrum compared to daylight. Dolphin Fin reads slightly lighter here — a subtle but real difference in how open the space feels.
Mudroom
A mudroom color needs to hold up under the most casual scrutiny: a glance as you're coming and going, often in mixed or artificial light. Dolphin Fin reads slightly lighter here — a subtle but real difference in how open the space feels.
