Tranquil Dawn vs Sea Salt
Where Tranquil Dawn belongs to Dulux's range, Sea Salt is a Sherwin-Williams color. These are both green-greys, so the question isn't which hue to choose — it's where within green-grey to land. Sea Salt (LRV 63) reflects noticeably more light than Tranquil Dawn (LRV 55), a difference of 8 points that becomes especially apparent in rooms with limited natural light. Both lean neutral, so they'll behave similarly in mixed or changing light conditions. The ΔE 5.7 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 8 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Tranquil Dawn vs Sea Salt in Real Spaces
8 real rooms side by side. Tranquil Dawn and Sea Salt 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
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 Sea Salt will make the room feel meaningfully brighter than Tranquil Dawn 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. Sea Salt reflects noticeably more light off the walls, making the space read more open than Tranquil Dawn.
Kitchen
In a kitchen, colors are seen under bright task lighting that amplifies undertones — what reads neutral elsewhere can show its hand here. Sea Salt reflects noticeably more light off the walls, making the space read more open than Tranquil Dawn.
Dining Room
A dining room lit by a dimmed pendant or candles is one of the most forgiving environments for paint — warm light softens almost everything. Sea Salt returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Bathroom
Bathrooms are one of the few spaces where you're genuinely enclosed by the paint color, which makes the choice between these two more consequential. Sea Salt reflects noticeably more light off the walls, making the space read more open than Tranquil Dawn.
Home Office
The test for a home office color isn't how it looks in a quick glance — it's whether it still feels right after a full day of work. Sea Salt reflects noticeably more light off the walls, making the space read more open than Tranquil Dawn.
Mudroom
Mudrooms are seen in passing, often under whatever light comes through the door — a context that favors colors with some depth. Sea Salt returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Kitchen Cabinets
Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. Sea Salt reflects noticeably more light off the walls, making the space read more open than Tranquil Dawn.

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.
