Black grey vs Iron grey
Both from RAL Classic's palette. Iron grey (LRV 12) reflects noticeably more light than Black grey (LRV 6), a difference of 6 points that becomes especially apparent in rooms with limited natural light. With a ΔE of 16.9, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
Black grey vs Iron 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.
