Stone Gray vs RAL 150-M
Where Stone Gray belongs to PPG's range, RAL 150-M is a RAL Effect color. Stone Gray reads as greige-grey, while RAL 150-M reads as beige-greige — two distinct hue families, not close cousins. RAL 150-M (LRV 33) reflects noticeably more light than Stone Gray (LRV 30), a difference of 3 points that becomes especially apparent in rooms with limited natural light. The ΔE 4.5 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Stone Gray vs RAL 150-M in Real Spaces
3 real rooms side by side. Stone Gray and RAL 150-M 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
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. The brightness difference is modest but present — RAL 150-M gives the walls a little more lift.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. RAL 150-M reads slightly lighter here — a subtle but real difference in how open the space feels.
Bathroom
Bathrooms are one of the few spaces where you're genuinely enclosed by the paint color, which makes the choice between these two more consequential. RAL 150-M reads slightly lighter here — a subtle but real difference in how open the space feels.

Stone Gray vs RAL 150-M Simulated Comparison
5 simulated room previews — drag the slider on each to see Stone Gray on one side and RAL 150-M 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.
