Mountain Air vs RAL 210-1
Where Mountain Air belongs to Benjamin Moore's range, RAL 210-1 is a RAL Effect color. Mountain Air reads as greige-grey, while RAL 210-1 reads as beige-greige — two distinct hue families, not close cousins. RAL 210-1 (LRV 57) reflects noticeably more light than Mountain Air (LRV 53), a difference of 4 points that becomes especially apparent in rooms with limited natural light. The ΔE 3.5 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.
