What color is Sherwin Williams Gibraltar?
Sherwin Williams Gibraltar SW 6257 is a medium-depth blue-gray with a quiet, weathered slate cast. Its muted blue character keeps it cool without reading overly bright, while the gray base gives it enough restraint for larger surfaces. In daylight, Gibraltar can appear cleaner and slightly bluer; under warm lamps, it tends to settle into a softer charcoal-gray. It suits a home office, powder room, or exterior siding, and also makes a grounded cabinet color against pale stone counters. Pair it with crisp white trim, light oak, aged brass, or warm tan leather to bring out its balanced gray-blue tone.

LRV of Gibraltar
Gibraltar has an LRV of 13.82% and refers to Medium Dark which means that this color reflects very little light. Why LRV is important?
Light Reflectance Value measures the amount of visible and usable light that reflects from a painted surface.
Simply put, the higher the LRV of a paint color, the brighter the room you will get.
The scale goes from 0% (absolute black, absorbing all light) to 100% (pure white, reflecting all light).
Act like a pro: When choosing paint with an LRV of 13.82%, pay attention to your bulbs' brightness. Light brightness is measured in lumens. The lower the paint's LRV, the higher lumen level you need. Every square foot of room needs at least 40 lumens. That means for a 200 ft2 living room you'll need about 8000 lumens of light – e.g., eight 1000 lm bulbs.
