Sea Emerald vs Black grey

Sea EmeraldJotunvsBlack greyRAL ClassicΔE 40.3Very different colors

Sea Emerald (Jotun) and Black grey (RAL Classic) come from different manufacturers. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. The 19-point LRV gap — 26 for Sea Emerald vs 6 for Black grey — means Sea Emerald will open up a space more effectively. A ΔE of 40.3 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.

Sea Emerald vs Black grey in Real Spaces

2 real rooms side by side. Seeing Sea Emerald 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

A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. Sea Emerald reflects noticeably more light off the walls, making the space read more open than Black grey.

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. Sea Emerald 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.
