Piano Concerto vs RAL 860-3
Where Piano Concerto belongs to Benjamin Moore's range, RAL 860-3 is a RAL Effect color. These are both greys, so the question isn't which hue to choose — it's where within grey to land. RAL 860-3 (LRV 54) reflects noticeably more light than Piano Concerto (LRV 51), a difference of 3 points that becomes especially apparent in rooms with limited natural light. The ΔE 3.8 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

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.
