Slippery Shale vs Anonymous
Slippery Shale (Behr) and Anonymous (Sherwin-Williams) come from different manufacturers. Both sit in the grey family, which is useful context if you're narrowing within a single hue direction. Their light reflectance values are nearly the same — 18 vs 20 — so neither will read significantly brighter or darker than the other. Where Slippery Shale leans red, Anonymous reads neutral — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 2.2 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Slippery Shale vs Anonymous in Real Spaces
1 real room side by side. Slippery Shale and Anonymous 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
A full exterior is the most demanding test for a paint color — scale and outdoor light both amplify differences that seem small on a swatch. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.

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