Cannon Ball vs Celestial Blue in Real Spaces
2 real rooms side by side. Seeing Cannon Ball and Celestial Blue 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. Celestial Blue reflects noticeably more light off the walls, making the space read more open than Cannon Ball.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. Celestial Blue returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
