Marina Gray vs Tranquil Dawn
Where Marina Gray belongs to Benjamin Moore's range, Tranquil Dawn is a Dulux color. Marina Gray reads as grey, while Tranquil Dawn reads as green-grey — two distinct hue families, not close cousins. Tranquil Dawn (LRV 55) reflects noticeably more light than Marina Gray (LRV 44), a difference of 11 points that becomes especially apparent in rooms with limited natural light. Marina Gray runs blue while Tranquil Dawn is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. The ΔE 7.7 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Marina Gray vs Tranquil Dawn in Real Spaces
4 real rooms side by side. Marina Gray and Tranquil Dawn are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
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 Marina Gray would.
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.
Mudroom
Mudrooms are seen in passing, often under whatever light comes through the door — a context that favors colors with some depth. Tranquil Dawn returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Kitchen Cabinets
Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. Tranquil Dawn reflects noticeably more light off the walls, making the space read more open than Marina Gray.

Marina Gray vs Tranquil Dawn Simulated Comparison
5 simulated room previews — drag the slider on each to see Marina Gray on one side and Tranquil Dawn on the other.
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.
