Santorini Blue vs Just Walnut in Real Spaces
2 real rooms side by side. Seeing Santorini Blue and Just Walnut 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. Just Walnut reflects noticeably more light off the walls, making the space read more open than Santorini Blue.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Just Walnut returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
