Whisper vs RAL 840-2
Whisper is a Benjamin Moore color while RAL 840-2 comes from RAL Effect. Whisper reads as grey, while RAL 840-2 reads as greige-grey — two distinct hue families, not close cousins. With LRVs of 66 and 66, they'll behave almost identically in terms of how much light they reflect back into a room. With a ΔE of 2.2, the difference is subtle — you'd need them side by side to reliably tell them apart. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Whisper vs RAL 840-2 in Real Spaces
1 real room side by side. Whisper 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.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.

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.
