Breton Blue vs Naval
Breton Blue (Dulux) and Naval (Sherwin-Williams) come from different manufacturers. These are both blues, so the question isn't which hue to choose — it's where within blue to land. The 6-point LRV gap — 10 for Breton Blue vs 4 for Naval — means Breton Blue will open up a space more effectively. Both share a cool character, which means they'll respond to light and surrounding materials in similar ways. ΔE 9.8 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 5 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Breton Blue vs Naval in Real Spaces
5 real rooms side by side. Breton Blue and Naval 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
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. Breton Blue reads slightly lighter here — a subtle but real difference in how open the space feels.
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. Breton Blue has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Dining Room
Dining rooms often rely on warm incandescent or candlelight, which flatters warm undertones and mutes cool ones. The brightness difference is modest but present — Breton Blue gives the walls a little more lift.
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. Breton Blue has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Breton Blue has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

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