Mountain Stream vs Agreeable Gray
Mountain Stream (PPG) and Agreeable Gray (Sherwin-Williams) come from different manufacturers. Mountain Stream reads as blue, while Agreeable Gray reads as greige-grey — two distinct hue families, not close cousins. The 19-point LRV gap — 60 for Agreeable Gray vs 41 for Mountain Stream — means Agreeable Gray will open up a space more effectively. A ΔE of 18.9 puts these firmly in different territory — two distinct design choices rather than close alternatives.

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.
