Britannia Blue vs Mineral Alloy
Britannia Blue and Mineral Alloy come from the same Benjamin Moore collection. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. The 10-point LRV gap — 28 for Mineral Alloy vs 18 for Britannia Blue — means Mineral Alloy will open up a space more effectively. Both share a blue character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 11.3 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Britannia Blue vs Mineral Alloy in Real Spaces
3 real rooms side by side. Seeing Britannia Blue and Mineral Alloy 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. Mineral Alloy reflects noticeably more light off the walls, making the space read more open than Britannia Blue.
Dining Room
Dining rooms often rely on warm incandescent or candlelight, which flatters warm undertones and mutes cool ones. The LRV gap is large enough that Mineral Alloy will make the room feel meaningfully brighter than Britannia Blue would.
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. Mineral Alloy returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Britannia Blue vs Mineral Alloy Simulated Comparison
5 simulated room previews — drag the slider on each to see Britannia Blue on one side and Mineral Alloy 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.
