Olympus Green vs Tranquil Dawn
Where Olympus Green belongs to Benjamin Moore's range, Tranquil Dawn is a Dulux color. Hue-wise, Olympus Green belongs to the blue-green family and Tranquil Dawn to the green-grey family. Tranquil Dawn (LRV 55) reflects noticeably more light than Olympus Green (LRV 9), a difference of 46 points that becomes especially apparent in rooms with limited natural light. Olympus Green runs blue while Tranquil Dawn is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 44.0, 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 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Olympus Green vs Tranquil Dawn in Real Spaces
3 real rooms side by side. Seeing Olympus Green 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 Olympus Green 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 Olympus Green.
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.

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.
