Warm Blue vs Black grey
Warm Blue (Jotun) and Black grey (RAL Classic) come from different manufacturers. Both sit in the blue-grey family, which is useful context if you're narrowing within a single hue direction. The 24-point LRV gap — 30 for Warm Blue vs 6 for Black grey — means Warm Blue will open up a space more effectively. A ΔE of 41.5 puts these firmly in different territory — two distinct design choices rather than close alternatives.

Warm Blue vs Black grey Simulated Comparison
5 simulated room previews — drag the slider on each to see Warm Blue on one side and Black grey on the other.
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.
