Deep Creek vs Porpoise
Where Deep Creek belongs to Benjamin Moore's range, Porpoise is a Sherwin-Williams color. These are both greige-greys, so the question isn't which hue to choose — it's where within greige-grey to land. They have nearly identical light reflectance values (15 vs 13), so they'll read as similarly Dark in most lighting conditions. Deep Creek runs red while Porpoise is decidedly warm, which means they'll respond very differently to warm vs cool light sources. At ΔE 0.8, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room. 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.
