Green Marble vs Lamp Black
Green Marble (Jotun) and Lamp Black (Little Greene) come from different manufacturers. Green Marble reads as green-grey, while Lamp Black reads as grey — two distinct hue families, not close cousins. The 11-point LRV gap — 13 for Green Marble vs 3 for Lamp Black — means Green Marble will open up a space more effectively. Where Green Marble leans neutral, Lamp Black reads purple — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 25.4 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Green Marble vs Lamp Black in Real Spaces
4 real rooms side by side. Seeing Green Marble and Lamp Black 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 Marble reflects noticeably more light off the walls, making the space read more open than Lamp Black.
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. Green Marble returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Dining Room
Dining rooms often rely on warm incandescent or candlelight, which flatters warm undertones and mutes cool ones. The LRV gap is large enough that Green Marble will make the room feel meaningfully brighter than Lamp Black would.
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. Green Marble returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Green Marble vs Lamp Black Simulated Comparison
5 simulated room previews — drag the slider on each to see Green Marble on one side and Lamp Black 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.
