Coastal Plain vs Magnetic Gray in Real Spaces
4 real rooms side by side. Coastal Plain and Magnetic Gray 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. Magnetic Gray reflects noticeably more light off the walls, making the space read more open than Coastal Plain.
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. Magnetic Gray returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
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. Magnetic Gray returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Front Door
On a front door, the color is both the first and last thing you see — a context where even a modest tonal difference reads clearly. Magnetic Gray reflects noticeably more light off the walls, making the space read more open than Coastal Plain.

5 simulated room previews — drag the slider on each to see Coastal Plain on one side and Magnetic Gray on the other.
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.
