Slippery Shale vs Ammonite
Slippery Shale (Behr) and Ammonite (Farrow & Ball) come from different manufacturers. Hue-wise, Slippery Shale belongs to the grey family and Ammonite to the beige-greige family. The 50-point LRV gap — 69 for Ammonite vs 18 for Slippery Shale — means Ammonite will open up a space more effectively. Where Slippery Shale leans red, Ammonite reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 36.7 puts these firmly in different territory — two distinct design choices rather than close alternatives.

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

Slippery Shale vs Ammonite Simulated Comparison
5 simulated room previews — drag the slider on each to see Slippery Shale on one side and Ammonite 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.
