Slippery Shale vs Green Smoke
Where Slippery Shale belongs to Behr's range, Green Smoke is a Farrow & Ball color. Slippery Shale reads as grey, while Green Smoke reads as green-grey — two distinct hue families, not close cousins. 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 Green Smoke is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. The ΔE 6.0 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Slippery Shale vs Green Smoke in Real Spaces
2 real rooms side by side. Slippery Shale and Green Smoke 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. The distinction reads clearly at room scale, making the choice between them concrete.
Kitchen Cabinets
Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. The distinction reads clearly at room scale, making the choice between them concrete.

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.
