Stonybrook vs Tranquil Dawn
Where Stonybrook belongs to Benjamin Moore's range, Tranquil Dawn is a Dulux color. Stonybrook reads as grey, while Tranquil Dawn reads as green-grey — two distinct hue families, not close cousins. Tranquil Dawn (LRV 55) reflects noticeably more light than Stonybrook (LRV 29), a difference of 26 points that becomes especially apparent in rooms with limited natural light. Stonybrook runs green while Tranquil Dawn is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 17.9, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.

2 real rooms side by side. Seeing Stonybrook 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
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 Tranquil Dawn will make the room feel meaningfully brighter than Stonybrook would.
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. Tranquil Dawn reflects noticeably more light off the walls, making the space read more open than Stonybrook.
