Newburyport Blue vs Breton Blue

Newburyport BlueBenjamin MoorevsBreton BlueDuluxΔE 1.2Subtle difference

Where Newburyport Blue belongs to Benjamin Moore's range, Breton Blue is a Dulux color. These are both blues, so the question isn't which hue to choose — it's where within blue to land. They have nearly identical light reflectance values (10 vs 10), so they'll read as similarly Dark in most lighting conditions. Newburyport Blue runs blue while Breton Blue is decidedly cool, which means they'll respond very differently to warm vs cool light sources. At ΔE 1.2, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room. Below you'll find 5 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.

Newburyport Blue vs Breton Blue in Real Spaces

Dining Room

A dining room lit by a dimmed pendant or candles is one of the most forgiving environments for paint — warm light softens almost everything. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.
