Osiris vs Green grey
Osiris (PPG) and Green grey (RAL Classic) come from different manufacturers. Hue-wise, Osiris belongs to the greige-grey family and Green grey to the green-grey family. The 3-point LRV gap — 13 for Green grey vs 10 for Osiris — means Green grey will open up a space more effectively. ΔE 4.2 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Osiris vs Green grey in Real Spaces
3 real rooms side by side. Osiris and Green grey 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.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.
House
A full exterior is the most demanding test for a paint color — scale and outdoor light both amplify differences that seem small on a swatch. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.
Front Door
On a front door, the color is both the first and last thing you see — a context where even a modest tonal difference reads clearly. The distinction reads clearly at room scale, making the choice between them concrete.

Osiris vs Green grey Simulated Comparison
5 simulated room previews — drag the slider on each to see Osiris on one side and Green grey on the other.
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.
