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