Deep Fossil vs Lamp Black
Where Deep Fossil belongs to Dulux's range, Lamp Black is a Little Greene color. These are both greys, so the question isn't which hue to choose — it's where within grey to land. Deep Fossil (LRV 31) reflects noticeably more light than Lamp Black (LRV 3), a difference of 28 points that becomes especially apparent in rooms with limited natural light. Deep Fossil runs neutral while Lamp Black is decidedly purple, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 41.1, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Deep Fossil vs Lamp Black in Real Spaces
4 real rooms side by side. Seeing Deep Fossil 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
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. The LRV gap is large enough that Deep Fossil will make the room feel meaningfully brighter than Lamp Black would.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. Deep Fossil reflects noticeably more light off the walls, making the space read more open than Lamp Black.
Dining Room
A dining room lit by a dimmed pendant or candles is one of the most forgiving environments for paint — warm light softens almost everything. Deep Fossil returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Bathroom
Bathrooms are one of the few spaces where you're genuinely enclosed by the paint color, which makes the choice between these two more consequential. Deep Fossil reflects noticeably more light off the walls, making the space read more open than Lamp Black.
