Dusty Miller vs RAL 840-2
Where Dusty Miller belongs to Benjamin Moore's range, RAL 840-2 is a RAL Effect color. Both sit in the greige-grey family, which is useful context if you're narrowing within a single hue direction. RAL 840-2 (LRV 66) reflects noticeably more light than Dusty Miller (LRV 59), a difference of 7 points that becomes especially apparent in rooms with limited natural light. The ΔE 3.9 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Dusty Miller vs RAL 840-2 in Real Spaces
2 real rooms side by side. Dusty Miller and RAL 840-2 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 brightness difference is modest but present — RAL 840-2 gives the walls a little more lift.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. RAL 840-2 reads slightly lighter here — a subtle but real difference in how open the space feels.

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.
