Smooth Stone vs Calcite
Smooth Stone (Sherwin-Williams) and Calcite (Tikkurila) come from different manufacturers. Hue-wise, Smooth Stone belongs to the greige-grey family and Calcite to the grey family. Their light reflectance values are nearly the same — 37 vs 35 — so neither will read significantly brighter or darker than the other. A ΔE of 1.3 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

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.
