Key Pearl vs Grey Blue
Key Pearl (Benjamin Moore) and Grey Blue (RAL Classic) come from different manufacturers. Key Pearl reads as pink-red, while Grey Blue reads as blue-grey — two distinct hue families, not close cousins. The 71-point LRV gap — 78 for Key Pearl vs 7 for Grey Blue — means Key Pearl will open up a space more effectively. A ΔE of 60.9 puts these firmly in different territory — two distinct design choices rather than close alternatives.

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.
