Deep Fossil vs Natural Slate
Deep Fossil and Natural Slate come from the same Dulux collection. Both sit in the grey family, which is useful context if you're narrowing within a single hue direction. Their light reflectance values are nearly the same — 31 vs 31 — so neither will read significantly brighter or darker than the other. Both share a neutral character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 2.6 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

5 simulated room previews — drag the slider on each to see Deep Fossil on one side and Natural Slate 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.
