Deep Space vs Tranquil Dawn

Deep SpaceBenjamin MoorevsTranquil DawnDuluxΔE 42.5Very different colors

Where Deep Space belongs to Benjamin Moore's range, Tranquil Dawn is a Dulux color. Hue-wise, Deep Space belongs to the blue-grey family and Tranquil Dawn to the green-grey family. Tranquil Dawn (LRV 55) reflects noticeably more light than Deep Space (LRV 11), a difference of 44 points that becomes especially apparent in rooms with limited natural light. Deep Space 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 42.5, 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.

Deep Space vs Tranquil Dawn in Real Spaces

4 real rooms side by side. Seeing Deep Space 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 Deep Space 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 Deep Space.

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.
