Fossil vs Just Walnut
Fossil is a Benjamin Moore color while Just Walnut comes from Dulux. These are both beige-greiges, so the question isn't which hue to choose — it's where within beige-greige to land. With LRVs of 72 and 72, they'll behave almost identically in terms of how much light they reflect back into a room. The tonal difference — Fossil's red character against Just Walnut's warm — becomes most visible against white trim or in morning light. At ΔE 5.2, the difference is perceptible but not dramatic — the two can work harmoniously in the same space. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Fossil vs Just Walnut in Real Spaces
2 real rooms side by side. Fossil and Just Walnut 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. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.
Kitchen Cabinets
On cabinetry, undertone and temperature become more pronounced against countertops and hardware. Side by side like this, the difference is easy to read — which is exactly why seeing them in a real space is more useful than comparing chips.

5 simulated room previews — drag the slider on each to see Fossil on one side and Just Walnut 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.
