Tranquil Dawn vs Krypton
Tranquil Dawn (Dulux) and Krypton (Sherwin-Williams) come from different manufacturers. Tranquil Dawn reads as green-grey, while Krypton reads as blue-grey — two distinct hue families, not close cousins. The 3-point LRV gap — 55 for Tranquil Dawn vs 52 for Krypton — means Tranquil Dawn will open up a space more effectively. Where Tranquil Dawn leans neutral, Krypton reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. ΔE 7.0 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 6 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Tranquil Dawn vs Krypton in Real Spaces
6 real rooms side by side. Tranquil Dawn and Krypton 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 reads slightly lighter here — a subtle but real difference in how open the space feels.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. Tranquil Dawn has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. Tranquil Dawn has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
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 has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Home Office
Home office walls matter more than most — you're looking at them all day, and a color that reads fine at first can become tiring over time. Tranquil Dawn has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Tranquil Dawn has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

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