Vapor Trails vs RAL 840-2
Where Vapor Trails belongs to Benjamin Moore's range, RAL 840-2 is a RAL Effect color. These are both greige-greys, so the question isn't which hue to choose — it's where within greige-grey to land. RAL 840-2 (LRV 66) reflects noticeably more light than Vapor Trails (LRV 61), a difference of 5 points that becomes especially apparent in rooms with limited natural light. At ΔE 2.6, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.

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.
