Dewberry vs Green Onyx in Real Spaces
2 real rooms side by side. Seeing Dewberry and Green Onyx 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. Green Onyx reflects noticeably more light off the walls, making the space read more open than Dewberry.
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. Green Onyx returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
