Just Walnut vs Light grey in Real Spaces
2 real rooms side by side. Just Walnut and Light grey 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
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. The LRV gap is large enough that Just Walnut will make the room feel meaningfully brighter than Light grey would.
Bathroom
Bathrooms are one of the few spaces where you're genuinely enclosed by the paint color, which makes the choice between these two more consequential. Just Walnut reflects noticeably more light off the walls, making the space read more open than Light grey.
