Living Room
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. The LRV gap is large enough that Purbeck Stone will make the room feel meaningfully brighter than Tranquil Aqua would.
Kitchen
In a kitchen, colors are seen under bright task lighting that amplifies undertones — what reads neutral elsewhere can show its hand here. Purbeck Stone reflects noticeably more light off the walls, making the space read more open than Tranquil Aqua.
