Gray Marble vs RAL 850-2
Gray Marble (PPG) and RAL 850-2 (RAL Effect) come from different manufacturers. These are both greys, so the question isn't which hue to choose — it's where within grey to land. Their light reflectance values are nearly the same — 46 vs 44 — so neither will read significantly brighter or darker than the other. ΔE 3.3 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.
Gray Marble vs RAL 850-2 in Real Spaces
3 real rooms side by side. Gray Marble and RAL 850-2 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
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. The distinction reads clearly at room scale, making the choice between them concrete.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. 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.

Gray Marble vs RAL 850-2 Simulated Comparison
5 simulated room previews — drag the slider on each to see Gray Marble on one side and RAL 850-2 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.
