Greenhouse vs Shamrock
Greenhouse and Shamrock come from the same Sherwin-Williams collection. These are both greens, so the question isn't which hue to choose — it's where within green to land. The NaN-point LRV gap — 6 for Shamrock vs NaN for Greenhouse — means Shamrock will open up a space more effectively. Where Greenhouse leans warm, Shamrock reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of NaN 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.
