Peppermint Rock vs RAL 740-2 in Real Spaces
2 real rooms side by side. Peppermint Rock and RAL 740-2 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
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 740-2.
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.
