Britannia Blue vs Treron
Where Britannia Blue belongs to Benjamin Moore's range, Treron is a Farrow & Ball color. Britannia Blue reads as blue-grey, while Treron reads as greige-grey — two distinct hue families, not close cousins. Treron (LRV 25) reflects noticeably more light than Britannia Blue (LRV 18), a difference of 7 points that becomes especially apparent in rooms with limited natural light. Britannia Blue runs blue while Treron is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 19.2, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Britannia Blue vs Treron in Real Spaces
4 real rooms side by side. Seeing Britannia Blue and Treron 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
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. The brightness difference is modest but present — Treron gives the walls a little more lift.
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. Treron has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Bathroom
Bathrooms are one of the few spaces where you're genuinely enclosed by the paint color, which makes the choice between these two more consequential. Treron reads slightly lighter here — a subtle but real difference in how open the space feels.
House
Seen across an entire facade, subtle tonal differences become pronounced. What reads as nearly the same on a chip often reads as clearly different at scale. Treron reads slightly lighter here — a subtle but real difference in how open the space feels.

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.
