Cathedral Gray vs Windmill Lane in Real Spaces
4 real rooms side by side. Seeing Cathedral Gray and Windmill Lane in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
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. Cathedral Gray reflects noticeably more light off the walls, making the space read more open than Windmill Lane.
Dining Room
Dining rooms often rely on warm incandescent or candlelight, which flatters warm undertones and mutes cool ones. The LRV gap is large enough that Cathedral Gray will make the room feel meaningfully brighter than Windmill Lane would.
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. Cathedral Gray returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Cathedral Gray returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
