Zen vs Tranquil Dawn
Zen (Behr) and Tranquil Dawn (Dulux) come from different manufacturers. These are both green-greys, so the question isn't which hue to choose — it's where within green-grey to land. The 9-point LRV gap — 55 for Tranquil Dawn vs 46 for Zen — means Tranquil Dawn will open up a space more effectively. Where Zen leans green, Tranquil Dawn reads neutral — a distinction that shifts noticeably depending on the light source and surrounding finishes. ΔE 5.5 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Zen vs Tranquil Dawn in Real Spaces
2 real rooms side by side. Zen 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
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. Tranquil Dawn reflects noticeably more light off the walls, making the space read more open than Zen.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. Tranquil Dawn returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

5 simulated room previews — drag the slider on each to see Zen 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.
