Warm Onyx vs Tanner's Brown
Warm Onyx (Behr) and Tanner's Brown (Farrow & Ball) come from different manufacturers. These are both greys, so the question isn't which hue to choose — it's where within grey to land. Their light reflectance values are nearly the same — 7 vs 7 — so neither will read significantly brighter or darker than the other. Where Warm Onyx leans red, Tanner's Brown reads neutral — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 1.6 puts them in subtle territory — distinguishable in direct comparison, less so from across a room.

Warm Onyx vs Tanner's Brown in Real Spaces
1 real room side by side. Warm Onyx and Tanner's Brown 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.
Living Room
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.

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.
