Caldwell Green vs Tranquil Dawn
Caldwell Green (Benjamin Moore) 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 39-point LRV gap — 55 for Tranquil Dawn vs 16 for Caldwell Green — means Tranquil Dawn will open up a space more effectively. Where Caldwell Green leans green, Tranquil Dawn reads neutral — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 32.4 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 5 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Caldwell Green vs Tranquil Dawn in Real Spaces
5 real rooms side by side. Seeing Caldwell Green 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
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 Caldwell Green.

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 returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

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.

Mudroom
In a hardworking space like a mudroom, the depth and warmth of a color reads differently than in a quieter room. The LRV gap is large enough that Tranquil Dawn will make the room feel meaningfully brighter than Caldwell Green would.

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 returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Caldwell Green vs Tranquil Dawn Simulated Comparison
5 simulated room previews — drag the slider on each to see Caldwell Green 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.
