Millstream vs Atmospheric
Millstream (Behr) and Atmospheric (Sherwin-Williams) come from different manufacturers. These are both blues, so the question isn't which hue to choose — it's where within blue to land. The 6-point LRV gap — 67 for Atmospheric vs 61 for Millstream — means Atmospheric will open up a space more effectively. Where Millstream leans blue, Atmospheric reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. ΔE 3.2 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

Millstream vs Atmospheric Simulated Comparison
5 simulated room previews — drag the slider on each to see Millstream on one side and Atmospheric 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.
