Black Mocha vs Warm Onyx
Both from Behr's palette. These are both greys, so the question isn't which hue to choose — it's where within grey to land. They have nearly identical light reflectance values (7 vs 7), 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. At ΔE 0.8, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Black Mocha vs Warm Onyx in Real Spaces
2 real rooms side by side. Black Mocha and Warm Onyx 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
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.
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. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.

Black Mocha vs Warm Onyx Simulated Comparison
5 simulated room previews — drag the slider on each to see Black Mocha on one side and Warm Onyx 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.
