Space Black vs Just Walnut
Where Space Black belongs to Benjamin Moore's range, Just Walnut is a Dulux color. Space Black reads as grey, while Just Walnut reads as beige-greige — two distinct hue families, not close cousins. Just Walnut (LRV 72) reflects noticeably more light than Space Black (LRV 5), a difference of 67 points that becomes especially apparent in rooms with limited natural light. Space Black runs neutral while Just Walnut is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 66.2, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

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.
