Smoke Gray vs S 5010-R90B

Their light reflectance values are nearly the same — 21 vs 19 — so neither will read significantly brighter or darker than the other. Where Smoke Gray leans blue, S 5010-R90B reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 2.3 puts them in subtle territory — distinguishable in direct comparison, less so from across a room.

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.
