Treasure vs Coastal Plain in Real Spaces
5 real rooms side by side. Treasure and Coastal Plain 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. Treasure brings more warmth to the space, while Coastal Plain keeps things cooler and crisper.
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. Coastal Plain reads more restrained here, while Treasure adds a sense of enclosure and warmth.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. Coastal Plain reads more restrained here, while Treasure adds a sense of enclosure and warmth.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. Coastal Plain reads more restrained here, while Treasure adds a sense of enclosure and warmth.
Home Office
Home office walls matter more than most — you're looking at them all day, and a color that reads fine at first can become tiring over time. Coastal Plain reads more restrained here, while Treasure adds a sense of enclosure and warmth.

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.
