Gibraltar vs Serious Gray
Gibraltar and Serious Gray come from the same Sherwin-Williams collection. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. The 9-point LRV gap — 23 for Serious Gray vs 14 for Gibraltar — means Serious Gray will open up a space more effectively. Both share a neutral character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 10.7 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.

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. Serious Gray returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

5 simulated room previews — drag the slider on each to see Gibraltar on one side and Serious Gray 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.
