Deep Fossil vs Windmill Lane
Deep Fossil (Dulux) and Windmill Lane (Little Greene) come from different manufacturers. Hue-wise, Deep Fossil belongs to the grey family and Windmill Lane to the green-grey family. Their light reflectance values are nearly the same — 31 vs 31 — so neither will read significantly brighter or darker than the other. Where Deep Fossil leans neutral, Windmill Lane reads green — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 10.5 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Deep Fossil vs Windmill Lane in Real Spaces
4 real rooms side by side. Seeing Deep Fossil and Windmill Lane 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
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. The distinction reads clearly at room scale, making the choice between them concrete.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.
Dining Room
Dining rooms often rely on warm incandescent or candlelight, which flatters warm undertones and mutes cool ones. 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.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.

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