Alloy vs Summit Gray
Both from Sherwin-Williams's palette. Both sit in the grey family, which is useful context if you're narrowing within a single hue direction. Summit Gray (LRV 30) reflects noticeably more light than Alloy (LRV 25), a difference of 4 points that becomes especially apparent in rooms with limited natural light. Both lean neutral, so they'll behave similarly in mixed or changing light conditions. The ΔE 5.2 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.

Alloy vs Summit Gray Simulated Comparison
5 simulated room previews — drag the slider on each to see Alloy on one side and Summit Gray on the other.
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.
