Porpoise vs Prospect
Both from Sherwin-Williams's palette. These are both greige-greys, so the question isn't which hue to choose — it's where within greige-grey to land. Porpoise (LRV 13) reflects noticeably more light than Prospect (LRV 10), a difference of 3 points that becomes especially apparent in rooms with limited natural light. Both lean warm, so they'll behave similarly in mixed or changing light conditions. The ΔE 5.6 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. 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.
