#5C5D5D
A gray screen color with a gray (balanced undertone) reading and LRV 11.0. Not sure it's the exact color your local store carries? Here's the closest match at each of the other four brands.
In a room
Knight's Armor is a deep balanced gray for cabinetry, media spaces, doors, or an accent zone that needs weight without a strong blue or brown cast. Light stone, pale wood, and warm metal can keep it from feeling severe. Low illumination makes it approach black. Test the actual finish under directional light and inspect the prepared surface carefully, since dark gray emphasizes sheen variation, patches, and small texture differences across large uninterrupted areas.

Yes. Put a labeled sample on the project surface and check it through the day beside trim, flooring, counters, textiles, and other fixed materials.
No. It reorganizes factual identifiers and screen values for comparison and links to the recorded source. It does not copy a fan deck layout or paint formula. In this library, the nearest cross-brand screen value is Ambler CW-685 by Benjamin Moore at ΔE 1.350.
