Greige vs RAL 840-3
Greige is a Behr color while RAL 840-3 comes from RAL Effect. Greige reads as grey, while RAL 840-3 reads as greige-grey — two distinct hue families, not close cousins. With LRVs of 46 and 46, 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.

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.
