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

5 simulated room previews — drag the slider on each to see Harlequin Blue on one side and Duck Green on the other.
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.
