Summer Day vs Black grey
Summer Day (Benjamin Moore) and Black grey (RAL Classic) come from different manufacturers. Summer Day reads as blue, while Black grey reads as blue-grey — two distinct hue families, not close cousins. The 45-point LRV gap — 52 for Summer Day vs 6 for Black grey — means Summer Day will open up a space more effectively. A ΔE of 59.0 puts these firmly in different territory — two distinct design choices rather than close alternatives.

5 simulated room previews — drag the slider on each to see Summer Day 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.
