Deep Fossil vs Bancha
Where Deep Fossil belongs to Dulux's range, Bancha is a Farrow & Ball color. Deep Fossil reads as grey, while Bancha reads as beige-greige — two distinct hue families, not close cousins. Deep Fossil (LRV 31) reflects noticeably more light than Bancha (LRV 13), a difference of 18 points that becomes especially apparent in rooms with limited natural light. Deep Fossil runs neutral while Bancha is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 25.6, 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 Bancha in Real Spaces
4 real rooms side by side. Seeing Deep Fossil and Bancha 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 Bancha 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 Bancha.
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 Bancha.

Deep Fossil vs Bancha Simulated Comparison
5 simulated room previews — drag the slider on each to see Deep Fossil on one side and Bancha 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.
