October Mist vs Tranquil Dawn
Where October Mist belongs to Benjamin Moore's range, Tranquil Dawn is a Dulux color. October Mist 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 October Mist (LRV 47), a difference of 8 points that becomes especially apparent in rooms with limited natural light. October Mist runs yellow while Tranquil Dawn is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. The ΔE 6.5 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.

October Mist vs Tranquil Dawn in Real Spaces
5 real rooms side by side. October Mist and Tranquil Dawn 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 Tranquil Dawn will make the room feel meaningfully brighter than October Mist 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. Tranquil Dawn reflects noticeably more light off the walls, making the space read more open than October Mist.
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. 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
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 October Mist.
Kitchen Cabinets
Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. Tranquil Dawn reflects noticeably more light off the walls, making the space read more open than October Mist.
