Begonia vs Mountain Stream
Begonia and Mountain Stream come from the same Sherwin-Williams collection. Hue-wise, Begonia belongs to the pink-red family and Mountain Stream to the blue family. Their light reflectance values are nearly the same — 26 vs 25 — so neither will read significantly brighter or darker than the other. Where Begonia leans warm, Mountain Stream reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 60.9 puts these firmly in different territory — two distinct design choices rather than close alternatives. 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.
