Both from RAL Classic's palette. Moss grey (LRV 20) reflects noticeably more light than Black grey (LRV 6), a difference of 14 points that becomes especially apparent in rooms with limited natural light. With a ΔE of 30.4, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
Moss grey vs Black grey Color Comparison
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.
