Deep Fossil vs Dix Blue
Deep Fossil is a Dulux color while Dix Blue comes from Farrow & Ball. Deep Fossil reads as grey, while Dix Blue reads as blue-grey — two distinct hue families, not close cousins. At LRV 41 vs 31, Dix Blue will read as the brighter of the two — a 10-point gap that matters most in north-facing or low-light rooms. The tonal difference — Deep Fossil's neutral character against Dix Blue's cool — becomes most visible against white trim or in morning light. At ΔE 13.3, these are genuinely distinct colors — a strong contrast if used together, or a meaningful choice between two different directions. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Deep Fossil vs Dix Blue in Real Spaces
4 real rooms side by side. Seeing Deep Fossil and Dix Blue 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
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. Dix Blue returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Bedroom
Bedroom walls are often seen under warm artificial light, a context that shifts both colors from how they look on a chip. The LRV gap is large enough that Dix Blue will make the room feel meaningfully brighter than Deep Fossil would.
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. Dix Blue reflects noticeably more light off the walls, making the space read more open than Deep Fossil.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The LRV gap is large enough that Dix Blue will make the room feel meaningfully brighter than Deep Fossil would.

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