Gray Stone vs RAL 830-1
Gray Stone (PPG) and RAL 830-1 (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. The 3-point LRV gap — 50 for RAL 830-1 vs 47 for Gray Stone — means RAL 830-1 will open up a space more effectively. A ΔE of 1.6 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Gray Stone vs RAL 830-1 in Real Spaces
3 real rooms side by side. Gray Stone and RAL 830-1 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. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.
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. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.
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. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.

Gray Stone vs RAL 830-1 Simulated Comparison
5 simulated room previews — drag the slider on each to see Gray Stone on one side and RAL 830-1 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.
