Blue Note vs Tranquil Dawn

Blue NoteBenjamin MoorevsTranquil DawnDuluxΔE 48.2Very different colors

Blue Note (Benjamin Moore) and Tranquil Dawn (Dulux) come from different manufacturers. Blue Note reads as blue-grey, while Tranquil Dawn reads as green-grey — two distinct hue families, not close cousins. The 46-point LRV gap — 55 for Tranquil Dawn vs 9 for Blue Note — means Tranquil Dawn will open up a space more effectively. Where Blue Note leans blue, Tranquil Dawn reads neutral — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 48.2 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.

Blue Note vs Tranquil Dawn in Real Spaces

5 real rooms side by side. Seeing Blue Note 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 Blue Note.

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.

Dining Room

Dining rooms often rely on warm incandescent or candlelight, which flatters warm undertones and mutes cool ones. The LRV gap is large enough that Tranquil Dawn will make the room feel meaningfully brighter than Blue Note would.

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.

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.

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.
