Mill Springs Blue vs Composed
Mill Springs Blue (Benjamin Moore) and Composed (Sherwin-Williams) come from different manufacturers. Mill Springs Blue reads as blue, while Composed reads as blue-green — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 34 vs 33 — so neither will read significantly brighter or darker than the other. Where Mill Springs Blue leans green and blue, Composed reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 1.7 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Mill Springs Blue vs Composed in Real Spaces
2 real rooms side by side. Mill Springs Blue and Composed are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
Living Room
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.

5 simulated room previews — drag the slider on each to see Mill Springs Blue on one side and Composed 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.
