Stonington Gray vs Tranquil Dawn in Real Spaces

6 real rooms side by side. Stonington Gray 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

A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. Stonington Gray reads slightly lighter here — a subtle but real difference in how open the space feels.

Bedroom

Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. Stonington Gray has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

Dining Room

Dining rooms often rely on warm incandescent or candlelight, which flatters warm undertones and mutes cool ones. The brightness difference is modest but present — Stonington Gray gives the walls a little more lift.

Kitchen Cabinets

Digital color is approximate.
