Deep Fossil vs Slate Lavender
Deep Fossil is a Dulux color while Slate Lavender comes from Jotun. Both sit in the grey family, which is useful context if you're narrowing within a single hue direction. At LRV 31 vs 25, Deep Fossil will read as the brighter of the two — a 6-point gap that matters most in north-facing or low-light rooms. They share a neutral quality — useful to know if you're layering them in the same space. At ΔE 4.8, the difference is perceptible but not dramatic — the two can work harmoniously in the same space. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Deep Fossil vs Slate Lavender in Real Spaces
3 real rooms side by side. Deep Fossil and Slate Lavender 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
Living rooms test a color across a full range of conditions — morning sun, afternoon shade, and evening lamp light all shift how both of these read. Deep Fossil has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Bedroom
Bedroom walls are often seen under warm artificial light, a context that shifts both colors from how they look on a chip. The brightness difference is modest but present — Deep Fossil gives the walls a little more lift.
Dining Room
Dining room light is typically the warmest in the house, which shifts both colors toward the red end of the spectrum compared to daylight. Deep Fossil reads slightly lighter here — a subtle but real difference in how open the space feels.

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