Britannia Blue vs Denim Drift
Britannia Blue is a Benjamin Moore color while Denim Drift comes from Dulux. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. At LRV 27 vs 18, Denim Drift will read as the brighter of the two — a 9-point gap that matters most in north-facing or low-light rooms. The tonal difference — Britannia Blue's blue character against Denim Drift's cool — becomes most visible against white trim or in morning light. At ΔE 10.0, 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.
Britannia Blue vs Denim Drift in Real Spaces
3 real rooms side by side. Britannia Blue and Denim Drift 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. Denim Drift returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
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. Denim Drift reflects noticeably more light off the walls, making the space read more open than Britannia Blue.
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 Denim Drift will make the room feel meaningfully brighter than Britannia Blue would.
