Trafalgar Grey vs Treron
Where Trafalgar Grey belongs to Dulux's range, Treron is a Farrow & Ball color. Trafalgar Grey reads as grey, while Treron reads as greige-grey — two distinct hue families, not close cousins. Treron (LRV 25) reflects noticeably more light than Trafalgar Grey (LRV 14), a difference of 11 points that becomes especially apparent in rooms with limited natural light. Trafalgar Grey runs neutral while Treron is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 18.0, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.

Trafalgar Grey vs Treron in Real Spaces
4 real rooms side by side. Seeing Trafalgar Grey 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 LRV gap is large enough that Treron will make the room feel meaningfully brighter than Trafalgar Grey would.
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 reflects noticeably more light off the walls, making the space read more open than Trafalgar Grey.
Kitchen
In a kitchen, colors are seen under bright task lighting that amplifies undertones — what reads neutral elsewhere can show its hand here. Treron reflects noticeably more light off the walls, making the space read more open than Trafalgar Grey.
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 returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
