Caffeine vs Warm Stone
Caffeine (Behr) and Warm Stone (Sherwin-Williams) come from different manufacturers. These are both greige-greys, so the question isn't which hue to choose — it's where within greige-grey to land. Their light reflectance values are nearly the same — 20 vs 20 — so neither will read significantly brighter or darker than the other. Where Caffeine leans red, Warm Stone reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 1.8 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Caffeine vs Warm Stone in Real Spaces
2 real rooms side by side. Caffeine and Warm Stone 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.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.

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