Delft vs Uncertain Gray
Both from Sherwin-Williams's palette. Delft reads as blue-grey, while Uncertain Gray reads as grey — two distinct hue families, not close cousins. Uncertain Gray (LRV 43) reflects noticeably more light than Delft (LRV 33), a difference of 10 points that becomes especially apparent in rooms with limited natural light. Delft runs cool while Uncertain Gray is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. The ΔE 8.7 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.

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.
