Vapor vs Just Walnut
Where Vapor belongs to Benjamin Moore's range, Just Walnut is a Dulux color. Vapor reads as beige-yellow, while Just Walnut reads as beige-greige — two distinct hue families, not close cousins. Vapor (LRV 82) reflects noticeably more light than Just Walnut (LRV 72), a difference of 10 points that becomes especially apparent in rooms with limited natural light. Vapor runs yellow while Just Walnut is decidedly warm, which means they'll respond very differently to warm vs cool light sources. The ΔE 7.3 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Vapor vs Just Walnut in Real Spaces
1 real room side by side. Vapor and Just Walnut 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 Vapor will make the room feel meaningfully brighter than Just Walnut would.

5 simulated room previews — drag the slider on each to see Vapor on one side and Just Walnut 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.
