Stone vs RAL 770-5
Stone is a Cloverdale Paint color while RAL 770-5 comes from RAL Effect. These are both greige-greys, so the question isn't which hue to choose — it's where within greige-grey to land. With LRVs of 42 and 43, they'll behave almost identically in terms of how much light they reflect back into a room. With a ΔE of 2.3, the difference is subtle — you'd need them side by side to reliably tell them apart. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Stone vs RAL 770-5 in Real Spaces
2 real rooms side by side. Stone and RAL 770-5 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.
Kitchen
Kitchen lighting tends to be bright and directional, which sharpens contrast and makes undertone differences more apparent. 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.
