Tranquil Dawn vs Grayish
Tranquil Dawn (Dulux) and Grayish (Sherwin-Williams) come from different manufacturers. Tranquil Dawn reads as green-grey, while Grayish reads as grey — two distinct hue families, not close cousins. The 5-point LRV gap — 60 for Grayish vs 55 for Tranquil Dawn — means Grayish will open up a space more effectively. Both share a neutral character, which means they'll respond to light and surrounding materials in similar ways. ΔE 6.6 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Tranquil Dawn vs Grayish in Real Spaces
3 real rooms side by side. Tranquil Dawn and Grayish 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. Grayish reads slightly lighter here — a subtle but real difference in how open the space feels.
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. Grayish has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Mudroom
In a hardworking space like a mudroom, the depth and warmth of a color reads differently than in a quieter room. The brightness difference is modest but present — Grayish gives the walls a little more lift.

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