Mountain Air vs Treron
Where Mountain Air belongs to Benjamin Moore's range, Treron is a Farrow & Ball color. These are both greige-greys, so the question isn't which hue to choose — it's where within greige-grey to land. Mountain Air (LRV 53) reflects noticeably more light than Treron (LRV 25), a difference of 28 points that becomes especially apparent in rooms with limited natural light. Both lean warm, so they'll behave similarly in mixed or changing light conditions. With a ΔE of 21.1, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.

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.
