Space Black vs Grey Blue
Space Black is a Benjamin Moore color while Grey Blue comes from RAL Classic. Space Black reads as grey, while Grey Blue reads as blue-grey — two distinct hue families, not close cousins. With LRVs of 5 and 7, they'll behave almost identically in terms of how much light they reflect back into a room. At ΔE 12.4, these are genuinely distinct colors — a strong contrast if used together, or a meaningful choice between two different directions.

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.
