Bachelor Blue vs Black grey

Bachelor BlueBenjamin MoorevsBlack greyRAL ClassicΔE 34.4Very different colors

Bachelor Blue (Benjamin Moore) 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 17-point LRV gap — 24 for Bachelor Blue vs 6 for Black grey — means Bachelor Blue will open up a space more effectively. A ΔE of 34.4 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.

Bachelor Blue vs Black grey in Real Spaces

3 real rooms side by side. Seeing Bachelor Blue and Black grey in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.

Living Room

Kitchen Cabinets

Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Bachelor Blue returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

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.
