Platinum Gray vs S 3005-G20Y
Platinum Gray is a Benjamin Moore color while S 3005-G20Y comes from NCS. These are both greys, so the question isn't which hue to choose — it's where within grey to land. With LRVs of 39 and 40, they'll behave almost identically in terms of how much light they reflect back into a room. They share a neutral quality — useful to know if you're layering them in the same space. With a ΔE of 1.8, the difference is subtle — you'd need them side by side to reliably tell them apart. 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.
