Peppermint Rock vs RAL 180-1 in Real Spaces
2 real rooms side by side. Seeing Peppermint Rock and RAL 180-1 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. Peppermint Rock reflects noticeably more light off the walls, making the space read more open than RAL 180-1.
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. Peppermint Rock returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
