Romney Wool vs Thames Fog in Real Spaces
3 real rooms side by side. Seeing Romney Wool and Thames Fog 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. Romney Wool reflects noticeably more light off the walls, making the space read more open than Thames Fog.
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 Romney Wool will make the room feel meaningfully brighter than Thames Fog 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. Romney Wool returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
