Stone Blue vs Treron
Both from Farrow & Ball's palette. Hue-wise, Stone Blue belongs to the blue family and Treron to the greige-grey family. Stone Blue (LRV 28) reflects noticeably more light than Treron (LRV 25), a difference of 3 points that becomes especially apparent in rooms with limited natural light. Stone Blue runs cool while Treron is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 20.0, 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 7 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Stone Blue vs Treron in Real Spaces
7 real rooms side by side. Seeing Stone 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 temperature contrast between Treron and Stone Blue is what sets these apart most in this context.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. Treron brings more warmth to the space, while Stone Blue keeps things cooler and crisper.
Kitchen
In a kitchen, colors are seen under bright task lighting that amplifies undertones — what reads neutral elsewhere can show its hand here. Treron brings more warmth to the space, while Stone Blue keeps things cooler and crisper.
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 brings more warmth to the space, while Stone Blue keeps things cooler and crisper.
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 brings more warmth to the space, while Stone Blue keeps things cooler and crisper.
Front Door
A front door is a focal point — small color differences read clearly at this concentrated scale. The temperature contrast between Treron and Stone Blue is what sets these apart most in this context.
Kitchen Cabinets
Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. Treron brings more warmth to the space, while Stone Blue keeps things cooler and crisper.

Digital color is approximate.
