Deep Fossil vs Denim Drift
Both from Dulux's palette. Deep Fossil reads as grey, while Denim Drift reads as blue-grey — two distinct hue families, not close cousins. Deep Fossil (LRV 31) reflects noticeably more light than Denim Drift (LRV 27), a difference of 4 points that becomes especially apparent in rooms with limited natural light. Deep Fossil runs neutral while Denim Drift is decidedly cool, which means they'll respond very differently to warm vs cool light sources. The ΔE 8.0 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Deep Fossil vs Denim Drift in Real Spaces
4 real rooms side by side. Deep Fossil and Denim Drift are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
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 brightness difference is modest but present — Deep Fossil gives the walls a little more lift.
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 reads slightly lighter here — a subtle but real difference in how open the space feels.
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 has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
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 reads slightly lighter here — a subtle but real difference in how open the space feels.

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