Blue Gossamer vs Black grey
Blue Gossamer (Behr) and Black grey (RAL Classic) come from different manufacturers. Blue Gossamer reads as blue, while Black grey reads as blue-grey — two distinct hue families, not close cousins. The 60-point LRV gap — 66 for Blue Gossamer vs 6 for Black grey — means Blue Gossamer will open up a space more effectively. A ΔE of 65.0 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.
Blue Gossamer vs Black grey in Real Spaces
3 real rooms side by side. Seeing Blue Gossamer 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. Blue Gossamer 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. Blue Gossamer 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. Blue Gossamer returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Blue Gossamer vs Black grey Simulated Comparison
5 simulated room previews — drag the slider on each to see Blue Gossamer 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.
