Frosted Fern vs Thames Fog in Real Spaces
2 real rooms side by side. Frosted Fern and Thames Fog 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. Frosted Fern reflects noticeably more light off the walls, making the space read more open than Thames Fog.
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. Frosted Fern returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

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.
