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.

Digital color is approximate.
