Slippery Shale vs Settlement
Where Slippery Shale belongs to Behr's range, Settlement is a Sherwin-Williams color. These are both greys, so the question isn't which hue to choose — it's where within grey to land. They have nearly identical light reflectance values (18 vs 19), so they'll read as similarly Dark in most lighting conditions. Slippery Shale runs red while Settlement is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. At ΔE 1.4, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room.
