Trafalgar Grey vs Tranquil Dawn
Both from Dulux's palette. Hue-wise, Trafalgar Grey belongs to the grey family and Tranquil Dawn to the green-grey family. Tranquil Dawn (LRV 55) reflects noticeably more light than Trafalgar Grey (LRV 14), a difference of 41 points that becomes especially apparent in rooms with limited natural light. Both lean neutral, so they'll behave similarly in mixed or changing light conditions. With a ΔE of 37.6, 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.
Trafalgar Grey vs Tranquil Dawn in Real Spaces
4 real rooms side by side. Seeing Trafalgar Grey and Tranquil Dawn 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 Tranquil Dawn 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. Tranquil Dawn 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. Tranquil Dawn 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. Tranquil Dawn returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Digital color is approximate.
