Functional Gray vs Rock Garden in Real Spaces
4 real rooms side by side. Seeing Functional Gray and Rock Garden 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. Functional Gray reflects noticeably more light off the walls, making the space read more open than Rock Garden.
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. Functional 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. Functional Gray returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
