Arrowhead vs Slippery Shale
Both from Behr's palette. Arrowhead reads as greige-grey, while Slippery Shale reads as grey — two distinct hue families, not close cousins. They have nearly identical light reflectance values (18 vs 18), so they'll read as similarly Dark in most lighting conditions. Both lean red, so they'll behave similarly in mixed or changing light conditions. The ΔE 4.3 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Arrowhead vs Slippery Shale in Real Spaces
1 real room side by side. Arrowhead and Slippery Shale are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
House
Seen across an entire facade, subtle tonal differences become pronounced. What reads as nearly the same on a chip often reads as clearly different at scale. Arrowhead brings more warmth to the space, while Slippery Shale keeps things cooler and crisper.

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