Windsurf vs Black grey

WindsurfBehrvsBlack greyRAL ClassicΔE 48.6Very different colors

Windsurf (Behr) and Black grey (RAL Classic) come from different manufacturers. Hue-wise, Windsurf belongs to the blue family and Black grey to the blue-grey family. The 31-point LRV gap — 37 for Windsurf vs 6 for Black grey — means Windsurf will open up a space more effectively. A ΔE of 48.6 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.

Windsurf vs Black grey in Real Spaces

3 real rooms side by side. Seeing Windsurf 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. Windsurf reflects noticeably more light off the walls, making the space read more open than Black grey.

House

A full exterior is the most demanding test for a paint color — scale and outdoor light both amplify differences that seem small on a swatch. Windsurf returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

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. Windsurf 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.
