Slippery Shale vs Treron
Slippery Shale (Behr) and Treron (Farrow & Ball) come from different manufacturers. Hue-wise, Slippery Shale belongs to the grey family and Treron to the greige-grey family. The 6-point LRV gap — 25 for Treron vs 18 for Slippery Shale — means Treron will open up a space more effectively. Where Slippery Shale leans red, Treron reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. ΔE 8.9 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Slippery Shale vs Treron in Real Spaces
2 real rooms side by side. Slippery Shale and Treron 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. Treron has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
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. Treron has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

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